Which set of ordered pairs represents a function? {(-4,9),(-5,4), (-5, -2), (1, -6)}

{(2,6), (5,1), (9,4),(2,-6)}

{(-7,-8), (0,1),(-3,9), (-4, -8)}

{(-6, -5),(-3,-4), (6,6), (-3,8)}

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

if you're trying to figure out how much each ounce cost it would be 0.20
