Enter the equation of the line in the form y=mx+b where m is the slope and b is the y-intercept.

y=3x-2

Why? Will you put the equation above but I found it by going up 3 on point (1,1) and left 1 to end up on point (4,2) because slope is rise/run you get 3. And the line intercepts the y axis at -2 so the answer is
Y=3x-2

Hope this helps
