Given the 3 points you entered of (7,21), (7,19), and (7,5), calculate the quadratic equation formed by those 3 points

Calculate Letters a,b,c,d from Point 1 (7, 21):
b represents our x-coordinate of 7
a is our x-coordinate squared → 72 = 49
c is always equal to 1
d represents our y-coordinate of 21

Write as Equation:
49a + 7b + c = 21

Calculate Letters e,f,g,h from Point 2 (7, 19):
f represents our x-coordinate of 7
e is our x-coordinate squared → 72 = 49
g is always equal to 1
h represents our y-coordinate of 19

Write as Equation:
49a + 7b + c = 19

Calculate Letters i,j,k,l from Point 3 (7, 5):
j represents our x-coordinate of 7
i is our x-coordinate squared → 72 = 49
k is always equal to 1
l represents our y-coordinate of 5

Write as Equation:
49a + 7b + c = 5
