FORMULAS

Question 1

DISTANCE FORMULA

Answer 1

d= √(x₂ - x₁) ² + (y₂ - y₁)²

Question 2

POINT SLOPE FORMULA

Answer 2

y-y₁=m(x-x₁)

Question 3

SLOPE FORMULA

Answer 3

(y2-y1)/(x2-x)

Question 4

EQUATION OF THE CIRCLE FORMULA

Answer 4

r^2= (x - h)^2 + (y - k)^2

Question 5

VERTEX FORMULA

Answer 5

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?

Question 6

LOGARITHIMIC FORMULA

Answer 6

loga^y = x

ex: log2^64= 6
2 x 2 x 2 x 2 x 2 x 2 = 64
