Slope = 1/3 y-intercept = - 1

Step-by-step explanation:

I think you wanted a graph ...

The y-intercept is the only part of the y axis where the line passes through.

So the slope is 1/3 - - rise/run

So from - 1 on the y axis, go up 1 and right 3

keep going until you run out of space and make a line.
