Answer:
Firstly, it is important to note that the multiplication of matrices is done in this way:
Columns x Rows or viceversa
Now, two matrices can be multiplied only if their dimensions are compatible, which means that the number of columns in the first matrix must be equal to the number of rows in the second matrix.
In other words:
Two matrices A and B are said to be multiplies if the number of columns in A coincides with the number of rows in B.
In this context, the correct option is:
![\left[\begin{array}{c}1&-1\end{array}\right] \left[\begin{array}{cc}0&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D1%26-1%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D0%264%5Cend%7Barray%7D%5Cright%5D)
Where A is:
![\left[\begin{array}{c}1&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D1%26-1%5Cend%7Barray%7D%5Cright%5D)
And B is:
![\left[\begin{array}{cc}0&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D0%264%5Cend%7Barray%7D%5Cright%5D)
As you can see, the number of columns in A coincides with the number of rows in B

Answer:
hmmmmm.ok
Step-by-step explanation:
Answer:
Y intercept = (0,10)
slope is 4
Step-by-step explanation:
Ok so Start with y intercept. That’s the point it crosses the y axis. So that would be ( 0, 10). To find slope, you do rise/run. Or how far up, and how far right. take two points (0,10) and (1, 14)
14-10
——-
1-0
= 4/1 = 4
so the slope is 4.
