You've already been provided a link to learn how to find the slope of the line L
_{1} through the points (-4, 0) and (0, 6), and the lesson at that link will also explain how the slope of L
_{1} relates to the slopes of all lines parallel to L
_{1}.
In case you're not familiar with how to plot points and draw lines (and this is why you haven't indicated having been able to get started on any portion of the exercise), you can learn about the x,y-plane
here. This lesson will explain, for instance, that the point (-4, 0) is found by starting at the "origin" (the place where the two arrow-lines, or "axes", cross), moving left by four units, going up
zero units, and then drawing a dot.
To learn how to graph lines from the slope (and the y-intercept), try
here. To learn how to graph lines in general, try
here.
Once you have learned the basic terms and techniques, please attempt the exercise. If you get stuck, you will then be able to reply with a clear listing of your work and reasoning so far. Thank you!
