Answer:
3) y = 2
4) y = -1x + 3
5) y = 3x - 3
6) x = -1
Explanation:
Start with y=mx+b for each equation and fill it in by looking at the graph.
y = don't fill out, that's a variable
m = the slope
x = don't fill out, that's a variable
b = where it intersepts the y-axis
(hopefully this is correct, it was slightly blurry, good luck and have a nice day!)
