Question

first correct answer gets a medal!
which is a solution of the equation?
2x-y=0
a.)3
b.)(2,-4)
c.)(3,-1)
d.)(1,2)

Answer 1

Well you have coordinates (x,y) just plug in the numbers and see which one works :)

Answer 2

So for example....from B

(2 , -4)

if we plug in the (x , y) we will have

2x - y = 0
2(2) - (-4) = 0
4 - (-4) = 0
8 = 0

Well that isn't correct...so that can't be the answer...

Answer 3

yeah

Answer 4

you get it yet ?
