Find the slope of the line through (9,0) and (3,8)

4/-3

Step-by-step explanation:

Slope (m) =  ΔY /ΔX  = 4 /-3

ΔX = 3 – 9 = -6

ΔY = 8 – 0 = 8

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
