Question

A taxi ride costs $3 plus $2.50 per mile. Write and GRAPH an equation in two variables that represents the total cost of a taxi ride. Let m represent number of miles and c represent the total cost (in dollars) of the taxi ride.

Answer 1

c = 2.5m + 3

Explanation:

because m is number of miles it is just like x in y = mx + b

c is basically y because it is the result

the equation is

c = 2.5m + 3

2.5 per mile and adding 3 for each trip

when graphing this your y intercept is at 3

2.5 is also 5/2 when turned into a fraction so you go up 5 and left 2 to find the next point on the line
