Write an equation for the line described. Give your answer in slope-intercept form.
-through $( - 7 , - 2 )$ and $( 0,2 )$
A) $y = - \frac { 4 } { 7 } x + 2$
B) $y = - \frac { 5 } { 2 } x + 2$
C) $y = \frac { 4 } { 7 } x + 2$
D) $y = \frac { 5 } { 2 } x + 2$

Question

Quizplus · Accepted Answer

The slope of the line through the points $(-7, -2)$ and $(0, 2)$ is $\frac{2 - (-2)}{0 - (-7)} = \frac{4}{7}$. The y-intercept is 2, so the equation is $y = \frac{4}{7}x + 2$.
