What is the slope of the line 4x - 2y = 10?

Rewrite the equation in slope-intercept form by solving for $y$. Starting with $4x - 2y = 10$, subtract $4x$: $-2y = -4x + 10$. Divide everything by $-2$: $y = 2x - 5$. The slope is the coefficient of $x$, which is 2, choice D. Choice A (4) is the $x$-coefficient in standard form, which is not the slope unless $y$'s coefficient is 1. Choice B ($-2$) is the $y$-coefficient. Choice C ($-5$) is the $y$-intercept. Another shortcut: in $Ax + By = C$, the slope is $-\frac{A}{B} = -\frac{4}{-2} = 2$.
