FORMULAS Flashcards
1
Q
DISTANCE FORMULA
A
d= √(x₂ - x₁) ² + (y₂ - y₁)²
2
Q
POINT SLOPE FORMULA
A
y-y₁=m(x-x₁)
3
Q
SLOPE FORMULA
A
(y2-y1)/(x2-x)
4
Q
EQUATION OF THE CIRCLE FORMULA
A
r^2= (x - h)^2 + (y - k)^2
5
Q
VERTEX FORMULA
A
y=a(x-h)^2 + k
ex: y= 2(x+3)^2 + 4
rewrite it into the vertex form: 2(x-(-3))^2 + 4
think: what made it positive?
6
Q
LOGARITHIMIC FORMULA
A
loga^y = x
ex: log2^64= 6
2 x 2 x 2 x 2 x 2 x 2 = 64
