Hi there!
There are multiple solutions to your question. Some possible solutions could be the following:
(0, -5)
(1, 0)
(2, 5)
Your answer would be 3160.
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
The area of the rectangular roof shingle is 70 inches
Any of the tens i think (10=60, 20+50, etc.), but i am not too sure what is implied by regrouping. if i am right in thinking this only means "carrying" a digit after adding, then anything that adds up to 70 would work unless the sum of the digits in the ones place exceeded 9.
