Exercise 9 Page 78

Substitute the given points into the Slope Formula.

-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=3- 9/0-( -3)
â–Ľ
Add and subtract terms
m=3-9/0+3
m=-6/3
â–Ľ
Simplify
m=-6/3
m=-2
The slope of the line that passes through the given points is -2.
