The line equation is .

First find the x-intercept, let y = 0.

                               (Replace y with 0)

                                      (Simplify)

Since x = when y = 0 graph the ordered pair (, 0)

To find the y-intercept, let x = 0.

                                (Replace x with 0)

                                       (Simplify)

Since y = when x = 0 graph the ordered pair (0, )

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (, 0) and (0, )
\
• Draw a line through these points.

Check:

Check by solving the equation for y.

                                (Write the equation)

                   (Subtract x from each side) \ \

If x = ,

                                (Product of two same signs is positive) \ \

                                       (Add: )

Notice that the graph of (, ) is on the line.
