Q.8
A taxi company charges a flat fee of $3.00 for using the taxi and an additional $0.75 per mile. Which of the following equations in slope-intercept form represents this situation? Let x represents the number of miles and y represents the total cost.
y = x + 0.75(3)
y = 3x + 0.75
y = 3x + 0.75x
y = 0.75x + 3
