Given the 3 points you entered of (25,7), (23,16), and (1,12):

Calculate the quadratic equation formed by those 3 points

Use Cramers Rule

b = x-coordinate of 25

a = x-coordinate squared
252 = 625

c is always equal to 1

d = our y-coordinate of 7

Determine values (e, f, g, h)

f = x-coordinate of 23

e = x-coordinate squared
232 = 529

g is always equal to 1

h = our y-coordinate of 16

Determine values (i, j, k, l)

j = x-coordinate of 1

i = x-coordinate squared
12 = 1

k is always equal to 1

l = our y-coordinate of 12
