A line passes through the points (-2, 9) and (1, 3).

Answer:

slope = -2

y-intercept = 5

Step-by-step explanation:

1) Find slope:

\frac{3-9}{1-(-2)} =  \frac{-6}{3} = -2

-2 = slope

2) Find y intercept trough point slope and slope-intercept forms

y - y1 = m (x - x1)

y - 9 = -2 (x + 2)

y - 9 = -2x -4

  + 9         + 9

y = -2x + 5

y = mx + b with b being the y-intercept

5 = y-intercept

Answer:

The answer is B.

Step-by-step explanation:

Its B because the lower the altitude the higher the pressure, and in this case the air towards the ground is being moved up, which is letting cold air sink back down.

What is the factorization of the following trinomial? 15x2 - 44x - 36
BartSMP [9]
15x^2-44x-36

=(15x^2+10x)+(-54x-36)

factor out  5x from 15x^2+10x  = 5x(3x+2)

Factor out -18 from -54x-36 =  -18(3x+2)

=5x(3x+2)-18(3x+2)

Factor out common term (3x+2)

= (3x+2)(5x-18)

hope this helps!
