Step-by-step explanation:
The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.
Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.
[ -8 2 2] { 3 }
[ 0 ]
[ -3]
= -8*3 + 2*0 + 2 * -3 = [-30] <-------- Answer.
Note a 1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.
Slope = (1+7)/(9+3) = 8/12 = 2/3
answer is B. 2/3
