SAT Question db0107df: Answer, Explanation & Desmos Solution

It's given that the y-intercept of the graph of $12 x + 2 y = 18$ in the xy-plane is $(0, y)$ . Substituting $0$ for $x$ in the equation $12 x + 2 y = 18$ yields $12 (0) + 2 y = 18$ , or $2 y = 18$ . Dividing both sides of this equation by $2$ yields $y = 9$ . Therefore, the value of $y$ is $9$ .
