Question

How do you find the slope and y intercept for `2x-y= 1`?

Answer 1

Put the `y`'s to one side, and the rest to the other.

Explanation:

Add `y` to both sides:
`->2x=y+1`
Now subtract `1` from both sides:
`->2x-1=y->y=2x-1`
In this the `2` that goes with the `x` is the slope,
and `-1` is the `y`-intercept at `(0,-1)`
graph{2x+1 [-14.24, 14.24, -7.11, 7.13]}
