Sam drives a delivery van. The equation C=0.5m+60 models the relation between his weekly cost, C, in dollars and the number of miles, m, that he drives. Interpret the slope and C-intercept of the equation. The slope, 60, means that the weekly cost, C, increases by $60 when the number of miles driven, m, increases by 1. The C-intercept means that when the number of miles driven is 0, the weekly cost is $0.50.

The slope, 0.5, means that the weekly cost, C, increases by $0.50 when the number of miles driven, m, increases by 1. The C-intercept means that when the number of miles driven is 0.50, the weekly cost is $60.

The slope, 0.5, means that the weekly cost, C, increases by $0.50 when the number of miles driven, m, increases by 1. The C-intercept means that when the number of miles driven is 0, the weekly cost is $60.

The slope, 60, means that the weekly cost, C, increases by $60 when the number of miles driven, m, increases by 1. The C-intercept means that when the number of miles driven is 60, the weekly cost is $0.50.
