Your graph should look exactly like the one below.

y = x + 2 (Black)

x + y = 3 (Red)

Now the solution is found in the intersection of the points, which is (0.5,2.5)

Verify:

y = x + 2

2.5 = 0.5 + 2

2.5 = 2.5 (correct)

Cheers

Tina babysits children in her neighborhood. When Tina is asked her rate, she tells her neighbors that she charges $15 for the fi

OLga [1]

The amount charged is an illustration of a linear equation.

Tina charges $39 for 4 hours

The given parameters are:

$Base = 15$ --- amount charged for the first hour

$Rate = 8$ --- amount charged for the extra hours

If Tina babysits for 4 hours, it means that:

She will charge $15 for the first hour
$8 for the extra 3 hours

So, the total charges is:

$Total = 15 + 3 \times 8$

$Total = 15 + 24$

$Total = 39$

The ordered pair is (4,39)

It means that:

She charges $39 for 4 hours
