Could someone explain to me how to solve this question?

write the equation of the line, in point-slope form. identify the point (-2, -2) as (x1, y1).

Step-by-step explanation:

A line is written in the point-slope form if its equation is in the form

where

is the slope of the line, calculated using the two points and

In this problem, we have the following two points:

Therefore we can calculate the slope of the line:

And so, the equation of the line in point-slope form is

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!
