Here's one way to construct the second triangle. See the attached image.
First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
Given that Eric knits 18 squares on monday, and knits seven more each day starting from Tuesday, this would mean that in tuesday, he knits a 25 squares, at wednesday, he knits 32 squares, at thursday, he knits 39 squares; therefore, on friday, the number of squares Eric knits is 46 squares. Hope this answers your question.

Step-by-step explanation:
I used distance formula to calculate. But if you haven't learned distance formula or solving radical equations, or solving equations by taking sq roots then maybe you were just supposed to graph it and look for the points. The answers came out to be nice neat numbers, so that is possible. x = 6 and x = 24
