The line equation is .

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

                               (Replace y with 0)

                  (Subtract 5 from each side)

                                         (Simplify)

Since x = 5 when y = 0 graph the ordered pair (5, 0)

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

                               (Replace x with 0)

                                          (Simplify)

Since y = 5 when x = 0 graph the ordered pair (0, 5)

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (5, 0) and (0, 5)
\
• Draw a line through these points.
