Question

Can someone help me with my algebra homework and explain how you got it ?

Answer 1

Answer: D

Explanation:

This problem seems to ask for the slope of the line. If not by counting, we can use the slope formula to solve. The formula is
`m=(y_(2)-y_(1) )/(x_(2)-x_(1) )`. Let's use (1,2) and (2,-1).

`m=(-1-2)/(2-1) =(-3)/(1)=-3`

Now, we know that the slope is -3.

We also know that A and C are eliminated because the line is going down, which signifies negative. We would be left with B and D. We know that B is incorrect because the slope would be less steep if B were to be the answer. Therefore, D is the correct answer.
