16. Graphs of equations with two variables Aa Aa suppose that the relationship between P and Qis glven by the equation Q so-SP. Solve the equation for P. P 10 50 O P- 10 (1/5)Q OP- 50 Q O 50-50 Plot the relationship between Pand Q on the following graph, noting that P is on the vertical axis and Qis on the horizontal axis. 40 Q so-SP 15 10 10 20 20 40 50 60 70 80 a Clear The slope of this line is Suppose that the P in this equation refers to the price Julie is willing to pay for an additional magazine, and the Q refers to the number of magazines to which Julie subscribes. Read the following statement carefully: \"The more magazines Julie subscribes to, the less she is willing to pay for an additional magazine. Which of the following best summarizes the pattern of causality suggested by this statement? O A change in P causes a change in Q. O The relationship between P and Q is not a causal relationship. Q A change in Q causes a change in P.

Solution

Solution:

1) Equation for P = 10 - (1/5)Q

2) Slope of the Line is 0.2

3) A change in Q causes a change in P

For plotting the graph to depict the relationship between P and Q for the equation Q = 50 - 5P,

JOIN 10 ON THE Y-AXIS TO 50 ON THE X-AXIS.
