The equation is .

(Write the equation in the form of y = mx + b)

Compare the equation with slope-intercept form y = mx + b.where m is slope and b is y-intercept.

slope(m) = 6 and y-intercept is(b) = 7.

y-intercept is 7, so the line crosses the y-axis at (0, 7)

Using slope find the next point.

Slope(m) = = .

• Plot the point (0, 7)
• Start at point (0, 7),since the rise is 6. Move 6 units down.
• The run is 1. Move 1 unit left then plot the point (, 1)
• Draw a line through these points.
