Look below!
Explanation:
Given equation is
As I've always stated, we can solve it in a simple 2-step manner, and this manner is the same for all linear equations.
- Step 1. Take
x=0 and solve fory . We will get0-y=1\impliesy=-1 So the first point of our consideration is(0,-1) . - Step 2. Next we take
y=0 and solve forx . We getx-0=1\impliesx=1 . So the next point in our consideration is(1,0)
So finding these 2 points and joining them through a line, we then extend the line on either sides to whatever length we see fit. So the graph will look a lot like this.
graph{x-y=1 [-2.5, 2.5, -1.25, 1.25]}
