#### Answer

x-intercept: $\quad 4$
y-intercept: $\quad 3$
.

#### Work Step by Step

The x-intercept is the value at which the graph crosses the x-axis (the y-coordinate is 0):
$3x+4(0)=12$
$3x=12$
$x=4$
The y-intercept is the value at which the graph crosses the y-axis (the y-coordinate is 0):
$3(0)+4y=12$
$4y=12$
$y=3$
Draw a line through $(4,0)$ and $(0,3).$
