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.

The line equation graph.
