How do you find the slope of a line on a xy coordinate plane?
Form a right angle triangle under the slope and divide the base of the triangle into the height of the triangle.
How do you find the base of a triangle if you know height and slope?
You cannot since the information is not sufficient. Furthermore, a triangle does not normally have a slope.
What are two lines that do not intersect and have the same slope?
triangle
Why is the slope equals to rise over run?
Because that's the definition of 'slope'.
What is the definition of slope?
Slope is the steepness of a line. From my high school math days, I remember that slope equals rise over run. Think of the sloping line as the hypotenuse of a right triangle, and the base is sitting on the x-coordinate. Rise is the length of the vertical leg of the triangle, and run is the length of the horizontal leg. Do the division, rise divided by run, and you have a measure of the slope. You might have to pay careful attention to positives and negatives. If it's a straight line you don't have to worry about how long you make the base; the ratio (the answer to a division problem) will be the same.
