What is the y-intercept of the quadratic function
f(x) = (x – 6)(x – 2)

A=1/2h(b1+b2) is the formula for the area of a a trapezoid b regular polygon c triangle d rhombus or kite

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.
