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

70

step-by-step explanation:

2*5=10

4*15=60

60+10=
