Algebra / Linear functions Difficulty: Easy

Argon is placed inside a container with a constant volume. The graph shows the estimated pressure $y$ , in $pounds per square inch (psi)$ , of the argon when its temperature is $x$ kelvins.

What is the estimated pressure of the argon, in $psi$ , when the temperature is $600$ kelvins?

Explanation

Choice B is correct. For the graph shown, the x-axis represents temperature, in kelvins, and the y-axis represents the estimated pressure, in $pounds per square inch (psi)$ . 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 $left parenthesis 600 comma 12 right parenthesis$ . This means that when the temperature is $600$ kelvins, the estimated pressure is $12 p s i$ .

Choice A is incorrect. This is the estimated pressure, in $psi$ , of the argon when the temperature is $300$ kelvins, not $600$ kelvins.

Choice C is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect. This is the temperature, in kelvins, of the argon.
