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?

Which expression gives the exact value of x?

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.
