Answer:
(-9, -26)
Step-by-step explanation:
y = (x - 1)2 - 6 and y = 4x + 10
Since they are both y =, you can set the two equations equal to each other:
(x - 1)2 - 6 = 4x + 10
2x - 2 - 6 = 4x + 10
-2 - 6 = 2x + 10
-8 = 2x + 10
2x = -18
x = -9
Check:
y = (x - 1)2 - 6
y = (-9 - 1)2 - 6
y = -18 - 2 - 6
y = -26
y = 4x + 10
y = 4 (-9) + 10
y = -36 + 10
y = -26
The answer to these equations is (-9, - 26). If you graph this, this is the point where the two graphs intersect.
