A(1,6)
B(1,8)

D(6,48)

Answer 1

Option B.(1,8)

Explanation:

Let

x ----> the number of hours worked

y ---->the amount earned in dollars

we know that

To find out the unit rate divide the total amount earned by the total hours worked

so

`(\$48)/(6)=\$8\ per\ hour`

That means

For x=1 hour, y=$8

therefore

The point that represent the unit rate is (1,8)
