Which of the following is the equation of a line parallel to the line y=3x+2, passing through the point (10,1)?
a) -3x+y=29
b) 3x-y=29
c) -3x+y=29
d) 3x+y=29

a

explanation:

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
