A. 3
B. 1/3
C. -3
D. -1/3

D

Step-by-step explanation:

This is a negative slope since it is going from left to right so that leaves you with c or d.

The slope is rise over run so in this case the rise is 1 and the run is -3 since its going left.

This leads you to -1/3

Hope this helped :)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
