Answer:
B ( -1, -8)
Step-by-step explanation:
A ( -7, -6)
midpt (-4, -7)
Equation:
(x + 3, y - 1)
Solve for B:
(-4, -7)
(x + 3, y - 1)
( -1, -8)
A.15 b.500 c.40 d.7.5 yeah, not to confident but I think it's correct.
Rigid transformation preserves both the side lengths and angle measures of a polygon.
{ 8, -6 } as you multiply the first equation with 1.25 to get :

then, you use elemination by substraction to get rid of x:

try to solve for y to get y = -6, and then you use either equation 1 or 2 to find the value of x, which in both cases is equal to 8.
