The graph in the attached figure
Step-by-step explanation:
we have
![x-y=1](/tpl/images/0459/4775/f26f9.png)
This is a linear equation
Isolate the variable y
![y=x-1](/tpl/images/0459/4775/5fea9.png)
we know that
The slope of the line is positive ![m=1](/tpl/images/0459/4775/52210.png)
The x-intercept is the point
----> value of x when the value of y is equal to zero
The y-intercept is the point
----> value of y when the value of x is equal to zero
Plot the intercepts to graph the line
see the attached figure
