Is should be (9-4x)•(9+4x)
Reflection that will produce an image with endpoints is y=-x
Answer:
20 degrees
Step-by-step explanation:
If BD is the angle bisector of ABC, then ABD must equal half of that. 40/2=20 degrees. Hope this helps!
(1,10)(-3,2)
slope = (2-10) / (-3-1) = -8/-4 = 2
y = mx + b
slope(m) = 2
(1,10)...x = 1 and y = 10
now we sub and solve for b, the y int
10 = 2(1) + b
10 = 2 + b
10 - 2 = b
8 = b
equation is : y = 2x + 8.....or 2x - y = -8
