Answer
x-intercept: $(10, 0)$
y-intercept: $(0, -30)$
Refer to the graph below.
Work Step by Step
To find the x-intercept, set y=0, then solve for $x$:
$y=-30+3x
\\0=-30+3x
\\30=3x
\\\frac{30}{3}=\frac{3x}{3}
\\10=x$
Thus, the x-intercept is $(10, 0)$.
To find the y-intercept, set x=0, then solve for $y$:
$y=-30+3x
\\y=-30+3(0)
\\ y=-30+0
\\y=-30$
Thus, the y-intercept is $(0, -30)$.
Plot the intercepts on the same coordinate plane, then connect the two points using a line. Refer to the attached image in the answer part above for the graph.
