For the following exercises, express the equations in slope intercept form (rounding each number to the thousandths place). Enter this into a graphing calculator as Yl, then adjust the ymin and ymax values for your window to include where the y -intercept occurs. State your ymin and ymax values. 49. 200 − 30 y x = 70

At sea level, the air pressure is 15 psi. As the vehicle goes underwater, the pressure
increases and as it goes up into the air, pressure decreases. The graph given below
