#### Answer

$y=3x-5$

#### 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=3, therefore its tentative equation is $y=3x+b$.
The y-intercept is (0, -5) therefore $b=-5$.
Thus, the equation of the line is $y=3x-5$.
