Answer
$y=-\frac{3}{8}x+12$
Work Step by Step
RECALL:
(i) The slope-intercept form of a line's equation is $y=mx+b$, where m=slope and b=y-intercept.
(ii) The line passes through the y-axis at the point (0, b).
The given line has $m=-\frac{3}{8}$, therefore its tentative equation is $y=-\frac{3}{8}x+b$.
The y-intercept is (0, 12), therefore $b=12$.
Thus, the equation of the line is $y=-\frac{3}{8}x+12$.
