If A = (7,9) and B = (3 , 12) what is the length of AB

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

d =

with (x₁, y₁ ) = A(7, 9) and (x₂, y₂ ) = B(3, 12)

AB =

      =

      =

      =

       = 5

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
