Step-by-step explanation:
Reflection across the y-axis replaces the x-coordinate with its opposite.
73 and -23 hope this helped hon :)
y=-8x+9
plug in -8
y=-8(-8)+9
y=64+9
y=73
plug in 4
y=-8(4)+9
y=-32+9
y=-23
the equations is y=x+3-1
Answer: how about 90
Its a 360 if you multiply 90×4 you get 360 every side is 90 degrees
-3x+3x-(b÷2)=-3
0-(b÷2)=-3
-(b÷2)=-3
b=-2×-3=+6
=> b=6
