Agarbage truck and a dump truck each drive along a straight road between two points. using the points on a map that the city created, the garbage truck will start at (–3, 4) and will stop at (5, 12). the dump truck will start at (5, –3) and will stop at (–4, 33).

what are the coordinates of the intersection that both trucks drive through?

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
