Answer:

y = 3x + 5

Explanation:

First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.

1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points

Using the two points first gives us a slope of 3

(1, 8) (2, 11)

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 - 8)/(2 - 1)

m = 3/1

m = 3

We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
