Answer:

The chosen topic is not meant for use with this type of problem. Try the examples below.

x + 6 y = 5

6 x + 2 y = 8

x − y + 4 = 8

Use the given functions to set up and simplify

2 .

x y =

− 1 =

3 =

− 1 =

2 =

0 − 4 = − 4

4 = − 4

2 = − 4

Explanation:

Find the equation with a point and y-intercept.

y = ( y/ x − y ) x + x y
