Answer:
Which are equivalent expressions?
Check all that are true.
y + x = 2x
x + x + x + x = 4x (true)
x + x = 2x (true)
x + y + y + x = 2x + 2y (true)
x + y + x + x = 2x + y

The answer in point form is (-1,0)
Answer:
This is a direct variation where the constant of variation is 5/9
Step-by-step explanation:
The equation for direct variation is y = kx
5x-9y =0
Lets try to get this equation in the above form
Add 9y to each side
5x-9y +9y = 9y
5x = 9y
Divide each side by 9
5/9 x = 9y/9
5/9x = y
This is in the form y = k x where k =5/9
