Please look in your text book for this problem Statement

The line equation is .

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

                (Substitute 0 for y)

                               (Simplify)

                          (Divide each side by 1.9)

                                        (Simplify)

The x-intercept is 2. So plot the point x-axis at (2, 0).

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

                (Substitute 0 for x)

                            (Simplify)

                    (Divide each side by negative 1.9)

                                     (Simplify)

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

Use these ordered pairs to graph the equation.

  • Draw a coordinate plane.
  • Plot the points (2, 0) and (0, )
  • Draw a line through these points.

graph the line equation 1.9x+1.9y=3.8 by using intercepts (2, 0) and (0, -2)

The line equation graph.

graph the line equation 1.9x+1.9y=3.8 by using intercepts (2, 0) and (0, -2)
