# Graph F(x)=x-4

F(x)=x-4
Rewrite the function as an equation.
y=x-4
Use the slope-intercept form to find the slope and y-intercept.
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
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
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
-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
-3
-3
The y value at x=1 is -3.
y=-3
y=-3
Create a table of the x and y values.
xy1-32-2
