Use the function rule, y = 2x + 5, to find the values of y when x = 1, 2, 3, and 4. Write the answers as ordered pairs that would be used to graph the function.

Answer 1

well I will do one of them

If x = 3
the answer will be ( 3 , something )
y = 2 (3) + 5
y = 6 + 5
y = 11
so
( 3 , 11 )

Answer 2

what does (3,11) represent and why is it there?

Answer 3

@so Damon... (3,11) is the ordered pair you would use to graph the function
