Shadow · Answer

what is x2

CC12 · Answer

slope?

Shadow · Answer

Yeah but that looks like x^2 which is a parabola

Shadow · Answer

that doesnt have a slope, so I assume you wrote the slope incorrectly.

CC12 · Answer

i did oops its x/2

CC12 · Answer

yes

CC12 · Answer

Thanks Shadow the answer was  y=-2x=10

Shadow · Answer

Point-Slope Form
$$y - y_{1} = m(x - x_{1})$$
$$y - 8 = -2(x - 1)$$
$$y - 8 = -2x + 2$$
$$y = -2x + 10$$

Yeah you're correct.
