Guided Practice Write an equation of a line with the given slope and y-intercept.

m = –1, b = –6

A.
y = x + 6

B.
y = –6x – 1

C.
y = –x – 6

Given tan∅=4/3 and π< ∅< (3π)/2; find cos2∅ a. -24/25 b. 24/25 c. -24/7 d. -7/25

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
