Question 36448: Graph the function.
f (x) = -2x – 5 ( , ) ( , )
State in words exactly where the points should be located. For example, if a set of coordinates is ( 2,3) you would say : From the origin count 2 spaces to the right on the x axis, then up 3 spaces and plot the point (2,3). *Always start each point from the origin – and you have to plot 2 points in order to draw the line.

You can put this solution on YOUR website! I am assuming that they want you to select two values of x, find the values of f(x) for each of these values of x, plot the points on a graph with a verbal description, and graph the result. Am I right???
First select two points, for x, ANY points that you want to plot. Let's pick the EASIEST points I can think of x = 0 and x =1.
f (x) = -2x – 5 (0 , ) ( 1 , )
If x = 0, then f(0) = -2(0)-5= -5. This means the point is (0,-5)
If x = 1, then f(1) = -2(1)-5=-7. This means the point is (1,-7)
State in words exactly where the points should be located. Since a set of coordinates is ( 0,-5) you would say : From the origin count 0 spaces to the right on the x axis, then down 5 spaces and plot the point (0,-5).
Next, the set of coordinates is (1,-7), so you would say: From the origin count 1 space to the right, then down 7 spaces, and plot the point (1, -7).
Now, connect the dots, and see if the graph agrees with this:
