Answer:
The answer to your question is: letter B
Step-by-step explanation:
Data
A (-5, 4)
B (4, 1)
Formula
slope = m =
m = =
Point slope
(y - 4) = (x + 5)
So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:
Next, add the two equations together to get . From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, the solution is (2,-5), or A.</u>
