Slope of a line

Slope is simply the change in the vertical distance over the change in the horizontal distance.

1) First, you have your points (4,9) (1,6).2)Next, you have to put it in y^2-y^1 6-9 -3M=------------- M=-------= -- x^2-x^1 1-4 -3 3)Lastly, you take -3/-3 and divide it and get 1.

Positive Slope- Goes up M>0Negative Slope- Goes down M<0Zero Slope- Goes horizontal M=0Undefined Slope- Goes vertical M is undefined.

(4,-6) (2,-3)M= -3--6 = -3 this is a Negative slope. 2-4 2(2,1) (8,9)M= 9-1 = 8 = 4 this is a positive slope. 8-2 6 3(-4,-1) (-4,-5)M= -3--3 = 0 = 0 this is a undefined Slope. 8-4 4
