A 5-mile cab ride costs $7.20. A 9-mile cab ride costs $11.60. Find a linear equation that models a relationship between cost c and distance d.

c = 1.44d + 4.40

d = 1.10c + 4.40

c = 1.29d + 1.70

c = 1.10d + 1.70

C - 7.2 = (11.6 - 7.2) / (9 - 4) (d - 5)

c - 7.2 = 4.4/4 (x - 5) = 1.1 (d - 5)

c = 1.10d - 5.5 + 7.2

c = 1.10d + 1.70

The last option is correct.

A 5-mile cab ride costs $7.20. A 9-mile cab ride costs $11.60. Find a linear equation that models a relationship between cost c and distance d.c = 1.44d + 4.40d = 1.10c + 4.40c = 1.29d + 1.70c = 1.10d + 1.70
