Question

Which of (3,5), (4,6), (5,7) and (6,8) are solutions to y=x+2

(3,5) and (4,6)
(4,6) and (5,7)
none
all

Answer 1

It's as easy as plugging in the x and y values and seeing if both asides are equal.

Answer 2

to check if (3,5) is a solution for example
you have to plug it into y = x+2
5 = 3 +2
5 =5
so (3,5) is a solution
can you try and check if (4,6) is also a solution ?
