Question #61963

Answer 1

`y=x+b` where `b` is the `y`-intercept.

Explanation:

The general slope-intercept equation for a line is

`y=mx+b`

`m` is the slope and `b` is the `y`-intercept (the `y`-value of the point where the line crosses the `y`-axis.

So, if the slope is one, (`m=1`), the equation looks a bit simpler

`y=x+b`

Once a value for `b` is given, the equation can be completed.
