Answer
$y=8x+4$
Work Step by Step
Use the slope formula $m=\frac{y^2-y^1}{x^2-x^1}$ and the point-slope form $y-y_1=m(x-x_1)$ to solve this problem.
$x$-intercept $=-\frac{1}{2}$ or $(-\frac{1}{2},0)$ and $y$-intercept $=4$ or $(0,4)$
$\frac{4-0}{0+\frac{1}{2}}=8$
$y-0=8(x+\frac{1}{2})$
$y-0=8x+4$
$y=8x+4$
