You can put this solution on YOUR website! Given:
.
x - y = 4
.
Subtract x from both sides to get rid of the x on the left side of the equation. Subtracting
x from both sides results in:
.
- y = -x + 4
.
But you need to solve for +y to get the equation into the slope intercept form. So change
the minus y to plus y by multiplying all terms on both sides of the equation by -1. When
you do that the equation becomes:
.
y = +x - 4
.
And that's the answer. It is in the form of y = mx + b in which m = +1 and b = -4.
The graph of this equation has a slope of +1 and it crosses the y-axis at -4. The graph looks
like this:

Hope this helps you to understand the problem a little more.
