1.2 is it as a decimal or 0.5
Given two coordinates point 1 as (-23,-14) and point 2 as(-18,2).
To find the midpoint we would use the formula below;

Where x1=-23, x2=-18, y1=-14, y2=2
We would substitute the values into the midpoint formula.

Therefore, the answer is
Answer: 2(x + 4)(x - 4)
Hope this helped!
X= 14 + 9y over 2
y= -x - 7 over 6
