Correct formula is y = kx, where k is the "constant of proportionality."
If y = 9 when x = 2, then 9 = k(2), or k = 9/2.
Then y = (9/2)x.
If x = 3, y = (9/2)(3) = 27/2 (answer)
-2 is the y-intercept

Answer:
-7.5
Step-by-step explanation:
Simplify
-4b - 5 + 2b = 10
-2b - 5 = 10
-2b = 15
b = -7.5
H + 121 + 31 = 180
H + 152 = 180
H = 180 - 152
H = 28
