The question gives us the equation x - y = 5, and we are told to find the slope of it. We can do this by solving the equation for the variable 'y,' which puts the equation into slope-intercept form, making it really easy to find the slope.
x - y = 5
-x -x
-y = -x + 5
(-1) (-1)
y = x - 5
Now that we have converted our original equation into slope-intercept form, we can easily find the slope. All we have to do is look at the coefficient of x, which is 1. Therefore, the slope of the graph is 1. Hope this helped!
