Answer:
y=5x
Explanation:
We can write this in slop-intercept form
Find the slope, rise/run = 10/2 = 5. So our slope is 5
Find the y-intercept which is 0
y=5x+0 or y=5x
Check it by plugging in a y value or x value
lets says we plugin 15, 15=5x and x=3
By looking at the graph we can see that it works
