Drawing straight line graph with large scale

Question

I was given the equation:

$$y(x) = 10000x + 150000 ,~~ 0 \lt x \lt 60$$

and was asked to draw the graph.

I know that it is a positive straight line intercepting through $150000$, but I don't know how to represent this on a graph as the scale is so large. When I tried to emulate it on my calculator I couldn't see the graph (presumably because its so large).

So how would I show this on a graph?

Answer 1

To graph the function, go to the "Window" screen. Set the $y$ limits to $y_{min}=-200,000,y_{max}=200,000$. Also, set the $x$ limits to $x_{min}=0,x_{max}=60$. Then, your graph will appear as a straight line intercepting through $150,000$.

Answer 2

Hint

If you plot this on paper, use 1 cm to represent 5 units along the $x$ axis (this will make a 12 cm $x$ axis) and use 1 cm to represent 50000 units along the $y$ axis (this will make a 15 cm $y$ axis).
