Answer is y = 6x + 3

Step by step

First we chose two points and find slope

(0, 3) and (2, 15)

y2 - y1 over x2 - x1
15- 3 over 2 - 0
12 over 2
slope or m = 6

We see from the table our y intercept is
at (0, 3) so our y intercept or b = 3

Our equation is

y = 6x + 3

Check on a graph and solution is correct!
