Answer:

y=4.5x +1.5

Step-by-step explanation:

First find your slope using y₂-y₁/x₂-x₁. In this case, your slope should come out to be 4.5. Now put your slope into slope-intercept form to get y=4.5x+b. Now to find the intercept, substitute any of the original coordinates in for x and y. I chose to use (2,7.5); the equation should now read 7.5= 2(4.5)+b. Solve the equation to get b=1.5. Now substitute everything back to slope-intercept form to get y=4.5x +1.5.

Hope this helps!
