The points (15,36) and (30,72) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
The slope is
(Simplify your answer.)

Step-by-step explanation:

Given coordinates;

                     (15,36) and (30,72)

Unknown:

Slope of the line  = ?

Solution:

     (15,36) and (30,72);

  Slope is the rise divided by the run. To find the slope, we use the expression below;

   Slope  =

y₁ = 36

y₂ = 72

x₁ = 15

x₂ = 30

  Insert the parameters and solve;

  Slope  =   =

 Slope  =

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

the answer

b. they are parallel and will never intersect.
