Graph x-y=1

Problem

x−y=1

Solution

1. Solve for y to put the equation into slope-intercept form y=m*x+b

x−y=1

−y=−x+1

y=x−1

2. Identify the y-intercept by looking at the constant term b

b=−1

Point=(0,−1)

3. Identify the slope by looking at the coefficient of x

m=1

Slope=1/1

4. Find a second point by starting at the y-intercept and applying the slope (rise over run).

Rise=1

Run=1

Point=(0+1,−1+1)=(1,0)

5. Plot the points (0,−1) and (1,0) on a coordinate plane and draw a straight line through them.

Final Answer

y=x−1
