The graph of the equation $y=4-2x$ is a straight line with points $(0,4)$ and $(2,0)$.

Work Step by Step

$$y=4-2x$$ To graph, get the intercepts by alternately setting the value of x and y to zero. If $x=0$, $y=4-2x$ $y=4-2(0)$ $y=4$ If $y=0$ $y=4-2x$ $0=4-2x$ $2x=4$ $x=2$ Thus, you'll have points $(0,4)$ and $(2,0)$.
