Hint: Use the slope formula (y2-y1)/(x2-x1)

If you forgot how to use a point and the given slope to write an equation in slope intercept form, please copy and paste the link into a browser for a refresher

Hint: plug in the slope for m and then plug in the coordinate point (x,y) to solve for the only variable you don't have, b (y-intercept)

If you don't remember how to write the equation to the graph that passes through two points, please watch the video below for a refresher.

Hint: first calculate the slope using the slope formula then choose a coordinate point (x,y) to plug in with your slope to find your missing b value
