5-40.

Let $A = \left(−2, 5\right)$ and $B = \left(5, −2\right)$

1. Find the distance between $A$ and $B$.

Use the distance formula or sketch the points and use the Pythagorean Theorem.

2. Write the equation of the line through $A$ and $B$ in both point-slope and slope-intercept form.

Substitute in either form.
