Answer:
y=4x
Explanation:
y=mx+b is our frame equation for a linear function.
b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0
y=mx+0
m= the slope, to find m you can either use the slope formula or plug in a point and solve for m
8=m(2) + 0
m=4
we don't need to put 0 in our final answer because it doesn't change anything
