Exercise 109 Page 105

To find the slope of the line

m,

we can substitute any two points that are on the line in the Slope Formula. We have five different points to choose from. We will choose

(2, 4)

and

(4, 10) .

m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}}

SubstitutePoints

Substitute $(4, 10)$ & $(2, 4)$

m = \frac{1 0 - 4}{4 - 2}

Subtract term

m = \frac{6}{2}

Calculate quotient

m = 3
