Question

Is (0, 0) a solution to y = -2x?

Answer 1

If you plug in x = 0 and y = 0, will you get a true equation?

Answer 2

No^

Answer 3

are you sure?

Answer 4

If x = 0 and y = 0, then

y = -2x

0 = -2(0)

which becomes what?

Answer 5

1) If you substitute x=0 in the equation you will y=-2(0)=0 and hence 0,0 would be a solution to this equation.
2)If you were to plot this function (which you can do at http://fooplot.com/) you would observe that the straight line passes through the origin.

Answer 6

So thatmake a solutionthanks^

Answer 7

Your welcome :)

Answer 8

yes, you will get 0=0, which is true
