Plot each set of points, and draw a line through them. Then give the equation of the line. $$ (-5,5),(0,5), \text { and }(3,5) $$

Write an equation of the line satisfying the given conditions. Give the final answer in slopeintercept form. (Hint: Recall the relationships among slopes of parallel and perpendicular lines in Section \(3.3 . .)\) Perpendicular to \(x-2 y=7 ; \quad y\) -intercept \((0,-3)\)

Find each quotient. $$ \frac{5-(-7)}{-4-(-1)} $$
