Answer:
y = -3x - 1
Step-by-step explanation:
Look at your line. It's a downward trend which means your slope is negative
slope is the m in y = mx+b
Your b is your y intercept or where the graph touches the y = 0 vertical line.
It cross at -1 value
Your slope value is determined by rise/run so in the case it goes down 3 values and across 1 value so its 3/1 but its negative so its -3/1
I believe it is 1. Function 2. Not a function 3. Function 4. Not a function. I hope this helps! :)
This is your perfect answer
