Answer
slope = 0
y-intercept = $-\frac{1}{3}$
Work Step by Step
RECALL:
(i) The graph of the equation $y=k$ is a horizontal line, where $k$ = the y-intercept.
(ii) A horizontal line has a slope of zero.
This means that the graph of given equation is a horizontal line with a slope of zero and a y-intercept of $-\frac{1}{3}$.
Thus, the given line has:
slope = $0$
y-intercept = $-\frac{1}{3}$
To graph this equation, perform the following steps:
(1) All points on the line $y=-\frac{1}{3}$ have a y-value of $-\frac{1}{3}$. Plot the points $(-3, -\frac{1}{3})$, $(0, -\frac{1}{3})$, and $(3, -\frac{1}{3})$
(2) Plot each ordered pair, and then connect the points using a line.
