The first two aren’t true, I can’t see the sign for the third one but since the other two aren’t correct I’d assume the right answer is the third choice.

Find an equation of the line that passes through the pair of points (-5, -9) and (2,-7)
vladimir1956 [14]

Answer:

y=0.3x - 7.6

Step-by-step explanation:

line: y=ax+b

a= Δy ÷ Δx

a= (-9 + 7) ÷ (-5 - 2)

a= -2 ÷ -7 = approximately 0.3

y=0.3x + b

Now you can fill in one of the points to find b (or both to make sure you got the answer right).

0.3 × 2 + b = -7

0.6 + b = -7

b = -7 - 0.6 = approximately -7.6

So: an equation of the line that passes through this pair of points is y=0.3x - 7.6

On a test, i would write as many decimals as possible if not said not to, to get the most exact answer. Also remember to keep calculating with the number on your calculator and not to round them off for the most exact answer.

What are two different way of factoring -3x-9? Select all that apply
Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

-3x - 9

Required

Factorize

The options are not given; So, I'll answer on a general term

-3x - 9

Express -9 as -3 * 3

-3x - 9 = -3x - 3 * 3

Then factorize 3 out of the expression as:

-3x - 9 = 3(-x - 3)

Another way is to factor -3 out of the expression as:

-3x - 9 = -3x - 3 * 3

-3x - 9 = -3(x + 3)
