The line equation is .

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

                         (Substitute 0 for y)

             (Subtract 7 from each side)

                             (Simplify)

              (Multiply each side by negative one)

                                    (Product of two same signs is positive)

The x-intercept is 7.So plot the point x-axis at (7, 0)

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

                      (Substitute 0 for x)

                                    (Simplify)

The y-intercept is 7.So plot the point y-axis at (0, 7)

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (7, 0) and (0, 7)
\
• Draw a line through these points.
