Please help if anyone can!!!

Question

I have multiple issues. first, i have a problem on iteration. i am given
(x,f(x)) and (x + d, f( x + d)), where x ranges from Xmin to Xmax and d = (Xmax - Xmin)/100. Draw the curve f(x) = X^3/100 - x + 10, where x ranges from -10 to 10 in this fashion. And am asked to draw a hundred line segments joining those points.
I have already figured that the distance d = 10-(-10)/100 which is equal to 0.2. Since i am told to draw 100 line segments, i figured that increasing -10 by .2 will take 100 iterations to get to 10.
Now my question is how do i use a "for" loop to represent the above statement. I have tried couple of them, but it doesn't seem right. example of the one i tried is:
let x = 10
for(i = -10; i < x; i++). I know this is wrong. Please help if anyone can. I will really appreciate and thanks in advance.

This program draws graphs of curves using iterations

public class DrawCubicApplet extends Applet
public void paint (Graphics g);
Graphics2D g2 = (Graphics2D)g;
double xscale = (getWidth() - 1.0) / (XMAX - XMIN);
double yscale = (getHeight() - 1.0)/ (YMIN - YMAX);
g2.scale (xscale, yscale);
g2.translate (-XMIN, -YMIN);
g2.setStroke (new BasicStroke(0));
final double Xmax = 10;
final double Xmin = -10;
final double Ymax = 15;
final double Ymin = 5;
double d = 0.2;
This is how far i have gotten. Now i don't know how to set up my 'for' loop for the x values. That is, how can i state that from -10 with an increment of 0.2 will take 100 iterations to get to 10. I hope am not confusing you. Below is the question
Question: Simply draw a hundred line segments joining the points (x,f(x)) and (x + d, f( x + d)), where x ranges from Xmin to Xmax and d = (Xmax - Xmin)/100. Draw the curve f(x) = X^3/100 - x + 10, where x ranges from -10 to 10 in this fashion.
