Find the distance between the two points if rounded to the nearest tenth (-6,6) and (-3,3)

3 units

Step-by-step explanation:

Given parameters:

    Coordinates = (-6,6) and (-3,3)

Unknown:

The distance between them = ?

Solution:

To find the distance between two points, we use the expression below;

    D  =

    x₁ = -6    x₂ = -3

   y₁ = 6       y₂ = 3

    D =   =

    D = 3 units

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
