M = -4/3 (slope stays the same)
so y= -4/3x + b
b = y intercept
without a point on the line I can’t figure out what exact line you were looking for but that equation with any value as b will give you a line parallel to the original.
150 + 20x, where x is the number of cellphones sold
For number 13 x=70 and y=115 hope this helped
This would =65. any more questions feel free to ask :) happy to help out
