Write a program in VB to evaluate X and output Y using the equation Y=mX+c.?

Question

Pls be quick.

Answer 1

I agree with Rawlyn !!

Answer 2

The easiest to do this is using a function. Procedures and functions encourages code reuse. Example below:

Public Function EvaluateX(m As Single, x As Single, c As Single) As Double
EvaluateX = (m * x) + C
End Function

Using the function:
Private Sub Form_Load
MsgBox EvaluateX(5, 6 ,7)
End Sub

Answer 3

From your question I understand that:
You enter values for x,m,c
You must find Y

First create your form:
---------------------------------
Label "X=" , TextBox1
Label "m=", TextBox2
Label "c=", TextBox3
Label "Y=mX+c"
Button "Evaluate"
---------------------------------

Double click the button
Now you can add your code:

Dim x as integer
Dim y as integer
Dim m as integer
Dim c as integer
x=TextBox1.Text
m=TextBox2.Text
c=TextBox3.Text
y=m*x+c;
MsgBox y

I hope I'm right. I'm not using VB anymore
C# rules!

Did you mean:
m,c -are constants
X is a varibile too
You must find out Y?

Answer 4

X=(Y-c)/m

Do the programming yourself, that's why your teacher gave you this assignment.
