Answer:
(-4, -1/2)
Step-by-step explanation:
Just by looking at the graph I can estimate that the midpoint of AB is (-4, -1/2) but we can also use midpoint formula to get a for sure answer.
Midpoint Formula: <em>((x1 + x2)/2, (y1 + y2)/2)</em>
x: (-5 + (-3))/2
-8 / 2
x = -4
y: (-4 + 3)/2
-1 / 2
y = -1/2
Answer:
<em><u>22x + 2</u></em>
Step-by-step explanation:
7x + 4 + 12x + 4 + 3x - 6
(*rearrange*)
7x + 12x + 3x + 4 + 4 - 6
= 22x + 2
