To multiply B and A, the number of columns of B must matc the number of rows of A.
<h3>
When we can multiply two matrices?</h3>
When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.
Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).
To multiply BxA:
Then, a row on matrix B must have the same number of elements than a column in row A.
Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.

Answer:
Plot the points (0,0) , (5, 4) and (-5, -4).
Step-by-step explanation:
You could plot three points. Then if they have been plotted correctly the graph will be a straight line joining these 3 points.
The 3 points could be
x y
0 0
5 4 ( 4 because y = 4/5 * 5 = 4)
-5 -4 ( y = 4/5 * -5 = -4).
