Slope of the line through the points (-12, -3) and (3, 7)
Answer: Slope is
Answer by sp75(12) (Show Source): You can put this solution on YOUR website! To find the slope between two points, you need to know what the slope is.
Imagine going up a hill. As you climb, you are going up some value, but in a way, you are still walking straight forward. It may sound a little confusing at first, but think of it this way, if walking up a hill meant walking straight up, you would be doing something similar to walking on a wall.
So, your slope is the up/sideways or rise/run as I have heard it most commonly called.
So, the formula to find the slope between two points is:
m = slope variable
y1 = the y component in the first point
x1 = the x component in the first point
y2 = the y component in the second point
x2 = the x component in the second point
m = (y2 - y1)/(x2-x1)
It shouldn't matter which point you use to pick for the first and second as long as x1 and y1 are in the same point and x2 and y2 are in the same point.
