Enter Point 1

Enter Point 2

Enter Point 3


Given the 3 points you entered of (25,13), (2,18), and (23,1):

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 13

Determine values (e, f, g, h)

f = x-coordinate of 2

e = x-coordinate squared
22 = 4

g is always equal to 1

h = our y-coordinate of 18

Determine values (i, j, k, l)

j = x-coordinate of 23

i = x-coordinate squared
232 = 529

k is always equal to 1

l = our y-coordinate of 1
