I learned this so many times but I forgot how to do it exactly.
But looking at this, you can already determine that y is equal to -3 so couldn't you use that as an answer.
Answer:
Step-by-step explanation:
First what you want to do is find the slope.
-3+3/1+3
0/4
slope=0
now you want to write the equation in point-slope form
y+3=0(x-1)
simplify
y+3=0
subract 3 from each sides
y=-3 is the answer
whatever x is, y is equal to -3
