Enter 3 points below:

<-- Point 1
<-- Point 2
<-- Point 3

Given the 3 points you entered of (4,13), (11,4), and (18,3):

Calculate the quadratic equation formed by those 3 points

Use Cramers Rule

b = x-coordinate of 4

a = x-coordinate squared
42 = 16

c is always equal to 1

d = our y-coordinate of 13

Determine values (e, f, g, h)

f = x-coordinate of 11

e = x-coordinate squared
112 = 121

g is always equal to 1

h = our y-coordinate of 4

Determine values (i, j, k, l)

j = x-coordinate of 18

i = x-coordinate squared
182 = 324

k is always equal to 1

l = our y-coordinate of 3
