There will be infinite answers for x if the equation if the same on both sides, so c=5
the easiest way I find a midpoint of two points is the midpoint theorem, here it is:

For x and y plug in the two coordinates given, (4,-4) & (0,8)
so once you plug the numbers into the equation you would get:
(2,2)
Answer:
Yes, he is correct
Step-by-step explanation:
if you translate each letter ABCDE to A"B"C"D"E" exactly how he stated it turns out right. For example, C just go 8 squares up and then 10 to the right and do the same for the rest.

Answer:
y = -2x + 6
Step-by-step explanation:
m=slope
b=y-intercept
(x, y) = (-1, 8)
y = mx + b
8 = -2(-1) + b
8 = 2 + b
b = 8-2
b = 6
y intercept = (0, 6)
y = -2x + 6
