Question

The solution for a system of two linear equations is (0, 0). Which equation below could be one of the equations in the system?

Answer 1

y= 1/3x + 4
y = –3x
y = 4x – 5
y = 5 – x

Answer 2

Plug in 0 for x and 0 for y in each answer choice.
Only one of those answers will be the same on both sides of the = sign
after plugging in and simplifiying

Answer 3

I tried to but I couldn't get an answer for any of them...

Answer 4

Plug in 0's for x an y in y= 1/3x + 4
What do you get?
0 = 1/3*0 + 4
0 = 4 incorrect..so it's not A

keep going

Answer 5

y = -3 which is 0 = -3(0).
so, 0 = 0? is that it?

Answer 6

that's it!

Answer 7

Awesome! thanks!
