Answer:

Answer below

Step-by-step explanation:

17. The points are (1,9) and (4,6)

y2 = 6, y1 = 9, x2 = 4 and x1 = 1

Slope m = (y2 - y1)/(x2 - x1)

Slope m = (6 - 9)/(4 - 1)

Slope m = -3/3

Slope m = -1

And the equation is

y - y1 = m(x - x1)

y - 9 = -1(x - 1)

y - 9 = -x + 1

y = -x + 1 + 9

y = -x + 10

y = 10 - x

Option E

18. Sin ∅ = opp/hyp

Sin∅ = 12/13
