Let and

*.*

Find the distance between

and.Plot the points and connect them. Then create a right triangle with segment

as the hypotenuse.

Use the Pythagorean Theorem to calculate the length of segment.Write the equation of the line passing through points

andin point-slope form and slope-intercept form.1. Determine the slope: rise/run.

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

3. Solve forfor the slope-intercept form.
