Answer:
y = 5x -6
Step-by-step explanation:
Dilation does not change the slope, but it moves the y-intercept by the dilation factor. The y-intercept of the original is -2. For the dilated line, the y-intercept will be 3(-2) = -6. The new equation is ...
y = 5x -6
_____
The graph shows the dilated line in blue. You can see that it is 3 times as far from the origin as the red line.
