find the equation of the straight line through the point (2,3) whose intercept on x-axis is twice that on y-axis​

y = -1/2x + 4

Step-by-step explanation:

y=mx+b

3 = m* 2 + b   .. pass (2,3)

y = 0       x = - b/m  .. x intercept

-b/m = 2b .... divide b both side

-1/m = 2           m= -1/2

b = 3 - 2m = 3 - (2*-1/2) = 4

equation:  y = -1/2x + 4

step-by-step 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
