Answer
$$x_{intercept} = (10, 0)$$ $$y_{intercept} = (0, 5)$$
Work Step by Step
To find the intercepts, one substitutes the opposite variable by zero and solves the equation. To find the $x_{intercept}$, for instance: $$-2x - 4(0) = -20$$ $$-2x = -20$$ $$x = 10$$ To find the $y_{intercept}$: $$-2(0) - 4y = -20$$ $$-4y = -20$$ $$y = 5$$ Finally, to draw the graph of the equation, one plots the intercepts and draws the line connecting them.
