What is the point slope form of (1,3) , (-1,4)

y - 3 = (x - 1)

Step-by-step explanation:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (4 - 3) / (-1 - 1)

             =

Point slope form:

y - y₁ = m(x - x₁)

y - 3 = (x - 1)

can be further simplify:

y - 3 = +

y - 7/2 = -1/2x

i'm not sure i quite understand, could you provide more information?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
