Answer:
y = 2x + 3
Explanation:
The slope can be found by taking two points, for instance: (0,3) and (3,9) which lie on the graph. Find the slope between the two, remember rise over run:
(9-3)/(3-0) = 6/3 = 2
The y-intercept is (0,3)
So b in the y= mx + b equation is 3.
m is the slope, so it is 2.
y = 2x + 3
