Last week, Sarah worked for 13 hours at her part time job. If she earned $143.00 for the week, how much did she earn per hour?

11 dollars an hour.

Step-by-step explanation:

143/13=11

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
