y=-1+x

Reorder -1 and x.

y=x-1

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=1

b=-1

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 1

y-intercept: -1

Slope: 1

y-intercept: -1

Choose 0 to substitute in for x to find the ordered pair.

Replace the variable x with 0 in the expression.

f(0)=(0)-1

Simplify the result.

Subtract 1 from 0.

f(0)=-1

The final answer is -1.

-1

-1

The y value at x=0 is -1.

y=-1

y=-1

Choose 1 to substitute in for x to find the ordered pair.

Replace the variable x with 1 in the expression.

f(1)=(1)-1

Simplify the result.

Subtract 1 from 1.

f(1)=0

The final answer is 0.

0

0

The y value at x=1 is 0.

y=0

y=0

Create a table of the x and y values.
