Exercise 64 Page 314

Substitute the given points into the Slope Formula.

H

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

SubstitutePoints

Substitute ( - 5,3) & ( 1,7)

m=7- 3/1-( - 5)

a-(- b)=a+b

m=7-3/1+5

Add and subtract terms

m=4/6

a/b=.a /2./.b /2.

m=2/3

The slope of the line that passes through the given points is 23. The correct choice is H.
