If the question is y = blank(x) + blank (I can’t see the left of the equation
Then the answer is y = 2x + -4
When two lines meet or cross that is call intersecting
Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
Look at the picture.
We have the proportion:
