so remember
(x,y)
we are given x=2
find what y is when x=2
subsitute 2 for x

y=2x+5
y=2(2)+5
y=4+5
y=9

so the blank is 9

when numbers are in parenthesis the first number is x the second is y

(x,y)

sine they give you (2, blank)

2 = x so replace x in the equation with 2

 so y=2x+5 becomes y=2(2)+5

 so y = 2*2+5 = 9

 y=9

 so it should be (2,9)
