-$m = - \frac { 2 } { 5 } ; b = 4$
A) $y = \frac { 2 } { 5 } x - 4$
B) $y = - \frac { 2 } { 5 } x - 4$
C) $y = \frac { 2 } { 5 } x + 4$
D) $y = - \frac { 2 } { 5 } x + 4$

Question

Quizplus · Accepted Answer

The equation of a line in slope-intercept form is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. Substituting $m = -\frac{2}{5}$ and $b = 4$ gives $y = -\frac{2}{5}x + 4$.
