Hey um wanna be friends lol?

Simplify a7/a4 a) 1/a3 b)-a/a2 c)a4/a3 d)a3

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

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?
