Answer:
It should be y=1/3x-1
Explanation:
equation without numbers: y=mx+b
M=Slope
B=Y-intercept
If you're looking for y you would do say on your x-axis it's 5 it would look like,
y=1/3x5-1
and then you're answer would be .65 as a fraction, I can't do that on my calculator.
Otherwise your answer would be y=1/3x-1
