Arnold deposited some money in a bank. The bank paid him a simple interest every year. After t years, the amount of money f(t), in dollars, that the bank paid Arnold was $1,000 more than 20 times the number of years. Which statement best describes the steps to sketch a graph showing the relationship between f(t) and t?

Label t on the x-axis and f(t) on the y-axis, and plot a graph having slope = 20 and y-intercept = 1000.
Label t on the x-axis and f(t) on the y-axis, and plot a graph having slope = 1000 and y-intercept = 20.
Label f(t) on the x-axis and t on the y-axis, and plot a graph having slope = 20 and y-intercept = 50.
Label f(t) on the x-axis and t on the y-axis, and plot a graph having slope = 1000 and y-intercept = 50.

Answer 5

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x?

Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67
Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67
