The Slope-Intercept form of the equation of a line is:

Where "m" is the slope of the line and and "b" is the y-intercept.
Knowing that the line passes through the points given in the exercise, you can find the slope with the following formula:

You can set up that:

Then substituting values, you get:

Substitute the slope and the coordinates of one of the points on the line into the equation

And solve for "b":

Then, knowing "m" and "b", you can determine that the equation of this line in Slope-Intercept form is:
