Work Step by Step
Find the $y$-intercept by setting $x$ to $0$. When $x$ is $0$, $y$ is $-3$, so the y-intercept is $(0,-3)$. Plot it.
Find the $x$-intercept by setting $y$ to $0$. When $y$ is $0$, $x$ is $3/4$, so the x-intercept is $(3/4,0)$. Plot it.
Connect these two points, and you get a line.
