Determine which of the following equations, when graphed, intersect at the point (4, 0).

Question

Select all that apply.

- x - y = 4
x - y = 4
2 x + y = 7
2 x + y = -7
x + y = 4
2 x - y = 7

Answer 1

- x - y = 4
x + y = 4

Answer 2

AAAaannndd the bot gets it wrong yet again!

clearly
-x-y = 4
does not contain the point (4,0)
you want
x+y=4
x-y = 4

Answer 3

I apologize for my mistake. You are correct that the equations that intersect at the point (4,0) are:

x+y=4
x- y = 4

Thank you for bringing this to my attention.
