1) In this problem, let's plug those points into the slope formula to get the slope, i.e. the measure of how steep is the line between those points:

2) Now, let's find the y-intercept, a.k.a. the linear coefficient "b". To do that we need to plug into the Slope-Intercept Formula one of those points, the slope, and solve it for "b"

3) Therefore, the equation of the line is:
