Topic: HELP ME PLEASE!!!

Hello everybody. I am really nervous about me being unable to solve this mistery. I insert a linear function f(x)= 409.30 * x and I see no function line on graph although it is checked show line. Acctualy, it shows a line which is paralel to y asix and it shouldn`t be like that. It shoud start from the cross point (O) and have an angle.  Here is a picture enclosed. Can enyone help me?

Re: HELP ME PLEASE!!!

Your picture is correct. Value 409.30 means tangent of the line angle, corresponding angle is 89.86°. Try to change the x-axis range from -0.1 to 0.1 to see more details.
