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 $(0,3).$
