First, we need to make the equation. We can use y = mx + b.
b is the y-intercept, and in this case, it is 20. Plug it in: y = mx + 20. Our first point on the graph is (0,20).
The slope is 0.005 (y = 0.005x + 20), which is too small to graph, if you look at the x-axis labels. But that's okay! Plug in a number for x that you know is on the x-axis, such as 2,000.
y = 0.005(2000) + 20 = 30
Remembering (x,y), we have our second point on the graph (2000, 30).
Let's look for one more.
y = 0.005(14000) + 20 = 90
Our third point on the graph is (14000, 90).
Now, lets look for those points on the graph and make our line.
