SAT Question d0cb49e8: Linear Functions answer and explanation with Desmos solution

Choice B is correct. For the graph shown, the x-axis represents temperature, in kelvins, and the y-axis represents the estimated pressure, in $\text{pounds per square inch}\left(psi\right)$. The estimated pressure of the argon when the temperature is $600$ kelvins can be found by locating the point on the graph where the value of $x$ is equal to $600$. The graph passes through the point $\left(600,12\right)$. This means that when the temperature is $600$ kelvins, the estimated pressure is $12$ psi.
