Answer 1

Answer:

(X,Y)

(2,2)

(4,3)

(7,4.5)

(9,5.5)

Step-by-step explanation:

To match the input values with the output, substitute each value on the right into the equation.

1) x

$y=\frac{(x)}{2}+1$

This doesn't change and it equal to y. So, map x with y.

2) 2

$y=\frac{(2)}{2}+1$

Divide:

$y=1+1$

Add:

$y=2$

So, match 2 with 2.

3) 4

$y=\frac{(4)}{2}+1$

Divide:

$y=2+1$

Add:

$y=3$

So, match 4 with 3.

4) 7

$y=\frac{(7)}{2}+1$

Divide:

$y=3.5+1$

Add:

$y=4.5$

So, match 7 with 4.5

5) 9

$y=\frac{9}{2}+1$

Divide:

$y=4.5+1$

Add:

$y=5.5$

So, match 9 with 5.5
