a_{1,3} = 9

Step-by-step explanation:

The elements of matrices are represented in the form

a_{r,c}

Here r is the row number and c is the column number.

Given matrix is:

A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]

The elements of matrix will be represented by a_{r,c}

We have to find a_{1,3}

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

So,

a_{1,3} = 9

Find an equation for the line that passes through the points (-5,-5) and (1,4)
Andreas93 [3]

The general line through (a,b) and (c,d) is

(c-a)(y-b)=(d-b)(x-a)

Here that's

(1 - - 5)(y - - 5) = (4 - -5)(x - - 5)

6(y+5)=9(x+5)

6y + 30 = 9x + 45

-15 = 9x - 6y

3x - 2y = -5

Answer: 3x - 2y = -5

We could put that in slope intercept form,

2y = 3x + 5

y = (3/2) x + 5/2

Answer: y = (3/2) x + 5/2
