x-intercept = $-2.5$ y-intercept = $-10$ Refer to the image below for the graph.
RECALL: The slope-intercept form of a line's equation is $y=mx+b$ where $m$ = slope and $b$ = y-intercept. The given equation is in slope-intercept form with $b=-10$ Thus, the y-intercept of the line is $-10$. To find the $x$ intercept, set $y=0$ then solve for $x$ to obtain: $y=-4x-10 \\0=-4x-10 \\0+10=-4x-10+10 \\10=-4x \\\dfrac{10}{-4} = \dfrac{-4x}{-4} \\-2.5=x$ The x-intercept is $-2.5$. To draw the graph of the equation, plot the x-intercept point $(-2.5, 0)$ and the y-intercept point $(0, -10)$ and connect them using a straight line.
