Answer:

B(2, 4)

Step-by-step explanation:

<u>Given points:</u>

A(-1, -9) and M(0.5, -2.5)

Let the coordinates of B are (x, y)

<u>Use midpoint formula to determine the point B:</u>

0.5 = (- 1 + x)/2 ⇒ 1 = -1 + x ⇒ x = 1 + 1 = 2
-2.5 = (-9 + y)/2 ⇒ -5 = -9 + y ⇒ y = -5 + 9 = 4

ICE Princess25 [194]

The final cost depends on the amount he buys since the 16.99 is the constant. Equation form is 16.99n where n is the amount hence the inconsistent variable
