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!
