Answer
$y=\frac{3}{8}x+7$
Work Step by Step
RECALL:
The slope-intercept form of a line's equation is $y=mx + b$ where $m$=slope and $(0, b)$ is the line's y-intercept.
The given line has a slope of $\frac{3}{8}$ (so $m=\frac{3}{8}$) and a y-intercept of $(0, 7)$ (so $b=7$).
Thus, the equation of the line in slope-intercept form is:
$y=\frac{3}{8}x+7$
