Answer 1

Answer:

Step-by-step explanation:

4). Parallel lines have the same slopes, but different y-intercepts.

(1, 2) and (6, 6): m = (6 - 2) / (6 - 1) = 4/5

m = 4/5 and point (9, 3), then y - 3 = 4/5(x - 9) ===> y = (4/5)x - 21/5

(6, 6) and (9, 3): m = (3 - 6) / (9 - 6) = - 1

m = - 1 and point (1, 2), then y - 2 = - (x - 1) ===> y = - x + 3
