hi
i'm looking for doing a programe that solve this equation y=m*x+b
where m is the slope and equal m=(y2-y1)/(x2-x1)
and b is the intersect with y axssis
now i wanna to enter 4 vlaues x1 ,x2,y1,y2 in textbox to clalculate the m and b
and this is easey now what i wanna and the problem is
according to x vlaue calculate the y vlaue where x is the numbers in rang from x1 to x2 and print the result in richtext box
any soulations??????????
here is my code please correct it thanks

{
InitializeComponent();
}
private void textBox5_TextChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
int x1, y1, x2, y2, m, b, y;
x1 = int.Parse(textBox1.Text);
y1 = int.Parse(textBox2.Text);
x2 = int.Parse(textBox3.Text);
y2 = int.Parse(textBox4.Text);
m = (y2 - y1) / (x2 - x1);
b = y1 - m * x1;
int x = x1;
while ( x <= x2)
{
y=m*x1+b;
richTextBox1.Text = Convert.ToString(y);
for (int i = x1; i<= x2; i++)
{
richTextBox1.AppendText(Convert.ToString(y));
}
x1 = x1 + 1;
}
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
MessageBox.Show("Thanks trying my programe");
}
}
}
