SAT Question 1efd8202: Linear Equations In Two Variables answer and explanation with Desmos solution

Choice A is correct. Each of the given choices gives three values of $x$: $0$, $2$, and $4$. Substituting $0$ for $x$ in the given equation yields $y=70\left(0\right)+8$, or $y=8$. Therefore, when $x=0$, the corresponding value of $y$ for the given equation is $8$. Substituting $2$ for $x$ in the given equation yields $y=70\left(2\right)+8$, or $y=148$. Therefore, when $x=2$, the corresponding value of $y$ for the given equation is $148$. Substituting $4$ for $x$ in the given equation yields $y=70\left(4\right)+8$, or $y=288$. Therefore, when $x=4$, the corresponding value of $y$ for the given equation is $288$. Thus, if the three values of $x$ are $0$, $2$, and $4$, then their corresponding values of $y$ are $8$, $148$, and $288$, respectively, for the given equation.
