Are P and Q positively or e. Compute the slope of the line. negatively related? b. Compute the intercept of the f. If Q increases by 2 units, does line on the P axis. [Hint: This P increase or decrease? is the value of P when Q = 0.] c. Compute the intercept of the g. By how many units? line on the Q axis. [Hint: This is the value of Q when P = 0.] d. Is the slope of the line positive or negative
