Answer:

The answer to your question is y = \frac{-1}{2} x - 1

Step-by-step explanation:

Process

1.- Get to points of the line

    A (-2, 0)

    B (0, -1)

2.- Find the slope of the line

Slope = m = \frac{y2 - y1}{x2 - x1}

Substitution

             m = \frac{-1 - 0}{0 + 2} = \frac{-1}{2}

3.- Find the equation of the line

              y - y1 = m(x - x1)

Substitution

              y - 0 = -1/2(x + 2)

Simplification

                   y = -1/2x - 1

Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d

<span>Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d. -18, -81, -144

Solution:

Since  it has to be between -13 and 89, letter d and b are not anymore considered to be the answer.

for a:
33-(-13)=46=d
43-33=10=d the value for this d is different from the two sequence,
89-43=46=d
they have different value for d, thus this is not the answer!

for c:
21-(-13)=34=d
55-21=34=d
89-55=34=d

they have the same value for d, thus the correct answer is </span><span> c. -13, 21, 55, 89</span>
