find two positive consecutive even integers such that the square of the smaller integer is decreased to five times larger than the integer 536

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 representation has a constant of variation of -2.5

Ineed to know the answer to this algebra question.
