Exercise 18 Page 91

Substitute the given points into the Slope Formula.

-3/2

Practice makes perfect

We can calculate the slope by substituting the given points into the Slope Formula. m = y_2-y_1/x_2-x_1 Note that it does not matter which point we choose to use for ( x_1, y_1) and ( x_2, y_2), since the result of using the Slope Formula will be the same.

m=y_2- y_1/x_2- x_1
m=- 2- 4/1.5-( - 2.5)
â–¼
Add and subtract terms
m=- 2-4/1.5+2.5
m=- 6/4
â–¼
Simplify
m=- 3/2
m=-3/2

The slope of the line that passes through the given points is - 32.
