Exercise 15 Page 91

Substitute the given points into the Slope Formula.

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

SubstitutePoints

Substitute ( - 2,6) & ( 1, 15)

m=15- 6/1-( - 2)
