Answer

\begin{align*} \text{$x$-intercept: }& \left(-\dfrac{5}{2}, 0\right) \\ \text{$y$-intercept: }& (0, 10) \end{align*}

Work Step by Step

To find the $x$-intercept of the given equation, $ -4x+y=10 ,$ substitute $y=0$ and then solve for $x.$ That is, \begin{align*} -4x+0&=10 \\ -4x&=10 \\\\ \dfrac{-4x}{-4}&=\dfrac{10}{-4} \\\\ x&=-\dfrac{10}{4} \\\\ x&=-\dfrac{5}{2} \end{align*} To find the $y$-intercept of the given equation, substitute $x=0$ and then solve for $y.$ That is, \begin{align*} -4(0)+y&=10 \\ 0+y&=10 \\ y&=10 \end{align*} Hence, the intercepts of the given equation are \begin{align*} \text{$x$-intercept: }& \left(-\dfrac{5}{2}, 0\right) \\ \text{$y$-intercept: }& (0, 10) \end{align*}
