y = 4x - 16
At the x-intercept, y=0.
0 = 4x - 16
Add 16 to each side:
16 = 4x
Divide each side by 4:
x = 4

x = 6.5y = 16.9
y = 2, 4, 6, 8
y =x^2-x-56 is the same as y = (x + 7)(x - 8)
y=2x2+5. Plug in 0 for x, and you get y=2(0)^2 +5 =0+5=5. 5 is the minimum value for y.
Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.
