Answer: y=5/2x
Explanation:
First of all, there is no y-intercept because it starts right at (0,0)
It RISES by 5 and RUNS by 2. That gives you the slope 5/2 because slope is RISE/RUN.
The slope equation is y=mx+b but since we don't have the b (it's zero) we just plug in the slope which is m.
Therefore the equation is y=5/2x :)
