Slope = -2
y - int = -4
y = -2x - 4
Two of the sides are the same (12) so the two angles at the top will also be the same, so you have two angles that are 62.
62 + 62 = 124
The three angles of a triangle need to equal 180.
X = 180-124 = 56
The answer is x = 56
Answer:
I would say D.) (6,-8)
Step-by-step explanation:
I say this because we're reflecting the point across the y-axis and if the y-axis is positive then the y-axis on the other number would be negative and we know that ordered pairs go like (x-axis, y-axis) and we know that that A prime is (6,8) so the ordered pair that hasn't been reflected would go like (6,-8)
(sorry if it doesn't make that much sense but I hope I helped you out some:))
