Question

find the midpoint of points a(-6, -10) and b(4, -4) graphically.
you may press submit or click the graph again to replot the midpoint.
(graph with coordinate plane, points a and b, and a dashed rectangle. buttons: start over, remove rectangle. answer section: midpoint: (□, □) submit answer)

Explanation:

Step1: Calculate x-coordinate of midpoint

Use midpoint formula for x: $\frac{x_A + x_B}{2} = \frac{-6 + 4}{2}$

Step2: Simplify x-coordinate

$\frac{-2}{2} = -1$

Step3: Calculate y-coordinate of midpoint

Use midpoint formula for y: $\frac{y_A + y_B}{2} = \frac{-10 + (-4)}{2}$

Step4: Simplify y-coordinate

$\frac{-14}{2} = -7$

Answer:

$(-1, -7)$
