Lindsay used two points, (x, y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

How do you solve a question like this?

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
