F(x)=x-4

Rewrite the function as an equation.

y=x-4

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=-4

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

Slope: 1

y-intercept: -4

Slope: 1

y-intercept: -4

Choose 2 to substitute in for x to find the ordered pair.

Replace the variable x with 2 in the expression.

f(2)=(2)-4

Simplify the result.

Subtract 4 from 2.

f(2)=-2

The final answer is -2.

-2

-2

The y value at x=2 is -2.

y=-2

y=-2

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

Replace the variable x with 1 in the expression.

f(1)=(1)-4

Simplify the result.

Subtract 4 from 1.

f(1)=-3

The final answer is -3.

-3

-3

The y value at x=1 is -3.

y=-3

y=-3

Create a table of the x and y values.
