SAT Question 8b2a2a63: Linear Equations In Two Variables answer and explanation with Desmos solution

It's given that the y-intercept of the graph of $y=-6x-32$ is $\left(0,y\right)$. Substituting $0$ for $x$ in this equation yields $y=-6\left(0\right)-32$, or $y=-32$. Therefore, the value of $y$ that corresponds to the y-intercept of the graph of $y=-6x-32$ in the xy-plane is $-32$.
