Select the choice which shows what the graph of the line represented by the equation y = -x + 4 looks like.

• The graph of the line y = -x + 4 is a straight line with a y-intercept at (0, 4) and a slope of -1.

• The graph of the line y = -x + 4 is a horizontal line

• The graph of the line y = -x + 4 is a parabola

• The graph of the line y = -x + 4 is a vertical line

Using a linear function, solve the problem: A car rental company charges a flat fee of $50 plus $20 per day for renting a car. Write the equation to represent the total cost (C) for renting a car for d days.

• C = 50d + 20

• C = 20d + 50

• C = 10d + 100

• C = 30d + 50
