Hi all,

I'm doing my final year maths project, and it has appeared to be a bit beyond my limits... It would be great if you helped me somehow!

So, I have 3 points from a graph and a general equation. With this data, I have to find a, b, and c of this equation.

The equation is:

While the points I'm given are: (1,0) and (4.5, 0.5) and (7.15,0.7)

As far as I know, I have to substitute x and y with given coordinates of points and solve a three unknowns system of equations. But to do so, I have to (probably) transform the equations to a form of 'a+b+c = x'.

Can you please tell me if I'm correct and whether it can be done?

Best wishes!
