Question

How do you graph `y+3=-1/3x`?

Answer 1

The equation is the same as `y=-1/3x-3`
Substitute any values for `x` and you'll get a y-coordinate.
You need a minimum of two coordinates to draw a line.
Go for easy x-values like x=0 and x=3
So when x=0,
`y=-3`
That's one coordinate (0, -3)
When x=3,
`y=-1-3=-4`
Second coordinate (3, -4)
Plot the two coordinates on a graph paper with the x and y axis.
Grab a ruler and draw a line that goes through the two points.
