Explain.

A flask is first evacuated so that it contains no gas at all. Then, 2.2 g of $\text{CO}_2$ is introduced into the flask. On warming to $22~^0\text{C}$, the gas exerts a pressure of 318 mm Hg. What is the volume of the flask?

Reduce the equations to slope-intercept form and find the slope and the $y$-intercept. Sketch each line

$$11.2x + 1.6 = 3.2y$$

determine whether the statement is true or false. Justify your answer. A linear equation will always have an x-intercept and a y-intercept.
