Write an equation in the form y = mx + b of the line that is described. The line has the same y-intercept as the line whose equation is y = - 2 + x and is parallel to the line whose equation is 3x + 3y = 6.

Square a has a side length of (2x-7) and square b has a side length of (-4x+18). how much bigger is the perimeter of square b than square a?and show all work! you so

Which of the following is best modeled using a linear equation y=ax+b, where a is less than 0?
