Answer:
y = 3x
Explanation:
slope intercept form is y = mx + b with m as the slope and b as the y-intercept
to find the slope you can see where the line intersects at (1, 3) and (0,0) If you look at the graph you count up three spaces over one so the slope is 3
since the y-intercept intersects at (0,0) The y-intercept is 0 and you do not have to add that to the answer
