Slope is defined as “rise over run,” with rise indicating vertical distance between two points, and run indicating the horizontal distance between two points. These can be any points the line runs through.  You can also use this method if you are given two points on the line, without having the line graphed in front of you. Coordinates are listed as (x,y){\displaystyle (x,y)}, with x{\displaystyle x} being the location along the x, or horizontal axis, and y{\displaystyle y} being the location along the y, or vertical axis. For example, you might choose points with coordinates (3,2){\displaystyle (3,2)} and (7,8){\displaystyle (7,8)}. One point will be point 1, and one point will be point 2. It doesn’t matter which point is which, as long as you keep them in the correct order throughout the calculation. The first point’s coordinates will be (x1,y1){\displaystyle (x_{1},y_{1})}, and the second point’s coordinates will be (x2,y2){\displaystyle (x_{2},y_{2})} The formula is riserun=y2−y1x2−x1{\displaystyle {\frac {rise}{run}}={\frac {y_{2}-y_{1}}{x_{2}-x_{1}}}}. The change in y-coordinates determines the rise, and the change in x-coordinates determines the run.

Summary: Understand the slope formula. Pick two points on the line and label their coordinates. Determine the order of your points. Set up the slope formula.


Warm sea salt water can help with pain and it may also help to heal an infection. To make a warm sea salt water rinse, mix about one teaspoon of sea salt with one cup of water. Stir until the salt dissolves in the water. Then, sip enough of the fluid to swish in your mouth and swish for about a minute. Spit out the fluid when you are done. Repeat this process several times throughout the day to help with pain and promote healing. Garlic has been shown to have some powerful antibacterial properties. Try using fresh garlic in a compress for a tooth infection. You can either use fresh, crushed garlic or one teaspoon of dried garlic powder mixed with one teaspoon of water.  To make the garlic compress, place the fresh crushed garlic or garlic powder paste into a clean nylon stocking. Gather the garlic into one small section of the nylon stocking so that it forms a small ball or lump. Then, apply the compress to the affected tooth and hold it there for about five minutes. Repeat this process four or five times per day. Some people use apple cider vinegar to help treat infections, so it might help with a tooth infection. Mix one teaspoon of apple cider vinegar with about one cup of water. Then, swish the solution in your mouth for about a minute and spit it out.  Repeat this rinse a few times per day. Clove oil may help ease some of the pain caused by an infected tooth. There is also some evidence that using a toothpaste that contains clove oil may be an effective treatment for plaque.  To use clove oil, put a few drops on a cotton swab and dab the oil onto the affected tooth. Leave the clove oil on your tooth for about three to five minutes. Then, rinse out your mouth with some salt water. Repeat this treatment four or five times per day.

Summary: Rinse with warm sea salt water. Make a garlic compress. Swish with apple cider vinegar. Apply clove oil.


Move the wheel left or right to maneuver your car in the direction of the spot.  You should approach the spot going no faster than 5 mph (8.0 km/h). This will help you pull into the spot at the right speed and not overshoot your target. This is particularly useful if you're parking in front of a wall and. It'll help you maintain control of the car. Take care to avoid hitting the curb or other cars in your way. Focus on your depth perception: have a firm sense of how close all of the objects in your way really are. Once you've pulled into the spot, it's time to firmly press down on the brake so the car comes to a complete stop. Keep your foot on the brake as you turn your wheels in the right direction. If you're pulling into a flat spot, just straighten your wheels. If you've parked uphill, you can turn your wheels away from the curb, and if you've parked downhill, you can turn your wheels toward the curb.  This will keep your car from rolling away if your brakes are disengaged. Shift to first gear (or reverse) and set the parking brake.  By leaving both the transmission and the parking brake engaged, you have 2 systems holding your car in place, which can help protect you in case one of them fails.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/fe\/Park-a-Car-Step-6-Version-2.jpg\/v4-460px-Park-a-Car-Step-6-Version-2.jpg","bigUrl":"\/images\/thumb\/f\/fe\/Park-a-Car-Step-6-Version-2.jpg\/aid639747-v4-728px-Park-a-Car-Step-6-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
Summary: Steer the car in the direction of the spot. Lightly place your foot on the brake. Pull into the parking space. Press down on the brake. Turn your wheels in the right direction. Set the parking brake in place.
