Question

which is a solution of the equation y=4x+3
(5,17)
(17,5)
(4,19)
(4,16)

Answer 1

substitute x and see which will be right

Answer 2

if you plug in values, which one will produce a true statement (like 2 = 2 )

Answer 3

example:
y = 4x + 3
plug in the point (5,17)
x=5, y=17

17 = 4*5 + 3

is this a true statement?
does
17 = 23 ?

Answer 4

Yes.

Answer 5

no, 17 does not equal to 23

Answer 6

therefore (5,17) is not a solution to the equation

Answer 7

Oh I was using the equation before you calculated 17=23

Answer 8

no problem :)

Answer 9

I understand it now, thanks. :)
