Okay so first you distribute to both sides(the arrows). then you subtract 5y to both sides and bring everything down. then you subtract 7 to both sides and get -27=9y and divide by 9 to get the y alone .
Right off the bat we know that the y-intercept is going to be 5 because of the second co-ordinate.
Now for the slope, because the y co-ordinate doesn't change, it has no slope so the equation is simply: y=5
Hope this helps :)

Answer:
The cost increase for each square of carpet by 12.
Step-by-step explanation:
The given function is
It is a slope intercept form of the line
Where m is the slope and b is y-intercept.
Therefore the slope of given function is 12 and the y-intercept is 50.
It means the initial ot fixed cost of the carpet is 50 and the cost increased by 12 for each square of carpet.
