Answer 1

@dyan, as you have two points, you are looking for a straight line through these two. The general equation for such a line is: y = m*x + b.

You need to find/calculate m and b from the two points that you already have. You can do this as follows:

Calculate m: m is defined as (y2 - y1)/(x2 - x1), where x1 and x2 are the x-coordinates and y1 and y2 are the y-coordinates of the two points you know.

If you have calculated m, you can plug that value into the equation y = m*x +b in order to find the value of b. Use one of the two points (x1,y1) or (x2,y2) and fill the x and y values into the equation. The only unknown is b. Solve for b, plug this b into the equation and you are done.

Can you apply this yourself ?
