The line equation is .

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

                          (Replace y with 0)

                      (Divide each side by 5)

                             (Simplify)

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

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

                        (Replace x with 0)

                              (Simplify)

Since y = 6 when x = 0 graph the ordered pair (0, 6)

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (6, 0) and (0, 6)
\
• Draw a line through these points.

Check by solving the equation for y.

                        (Write the equation)

              (Subtract x from each side)

                         (Simplify)

If x = 4,

                               (Subtract: )

Notice that the graph of (4, 2) is on the line.
