Answer

slope=$8$ y-intercept: $(0, 10)$

Work Step by Step

RECALL: The slope-intercept form of a line's equation is $y=mx+b$ where $m$= slope and $(0, b)$ is the line's y-intercept. Solve for $y$ to obtain: $y-8x+8x=10+8x \\y=10+8x \\y=8x+10$ This means the given equation is equivalent to, and has the same graph as, $y=8x+10$. This equation has: slope=$8$ y-intercept: $(0, 10)$
