Well the equation of a parabola is
substitute your points in one at a time then solve remaining system of equations.
Here's a kicker.
Now you have a go.
okay ill try some more now. ty
If you substitute the values into the general quadratic equation, then you get a linear system, which you can solve with substitution methodes.
