What is the first step when rewriting y = 3x2 9x – 18 in the form y = a(x – h)2 k? 3 must be factored from 3x2 9x x must be factored from 3x2 9x 9 must be factored from 9x – 18 3 must be factored from 3x2 – 18

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

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?

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?
