Answer:

D. 1 and 20

Step-by-step explanation:

To solve the equation, factor the quadratic and set the factors equal to 0.

d^2 - 21d + 20 becomes (d-20)(d-1) since -1*-20 = 20 and -1+-20 = -21.

Set each equal to 0 and solve for x.

d-20 = 0 d = 20

d - 1 = 0 d = 1

Answer:

D) y= -3x + 6

Step-by-step explanation:

y = mx + p

m = slope = (0-6)/(2-0) = -6/2 = -3

p = y-intercept = 6 ,because the line passes through points (0,6)
