2-13.

Plot the points and connect them. Then create a right triangle with segment *AB* as the hypotenuse.

Use the Pythagorean Theorem to calculate the length of segment *AB*.

1. Determine the slope: rise/run.

2. Substitute a given point and the slope into the point-slope formula.

3. Solve for *y* for the slope-intercept form.
