Exercise 59 Page 79

Substitute the given points into the Slope Formula.

-5/13

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 ( 3/2,-1/2) & ( -2/3,1/3)

m=1/3-( -1/2)/-2/3- 3/2
