Step-by-step explanation:

Given

Using the available details, the solution goes thus:

Solving (a): The slope (m) of this line:

This gives:

Simplify:

Solving (b): Another line with 1/3 of the slope.

This is calculated using:

i think the amount would be $140.62

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
