when you're finding slope with two given point you choose the second point of Y subtract the first point of Y. Second point of X subtract first point of X

slope is the change of Y over the Change of X

(3,9) is the second ordered pair so that will be you x2 and y2 because the point is after (0,3)

equation for slope: y2-y1/x2-x1

what you do is

9-3 = 6

3-0=3

6/3 if you simplify it it is 2.

the slope is 2

plug your numbers into the equation and isolate b which is the y intercept
