#### Answer

slope = $3$
y-intercept: $(0, -1)$
Refer to the graph below.

#### 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.
Thus, the equation $y=3x-1$ has a slope of $3$ and a y-intercept of $(0, -1)$.
To graph the equation, perform the following steps:
(1) Plot the y-intercept $(0, -1)$.
(2) Use the slope to plot a second point.
Since the slope of $3$, from $(0, -1)$, move 3 units up (the rise) and 1 unit to the right (the run) to reach the point $(1, 2)$. Plot $(1. 2)$.
(3) Connect the points using a straight line.
