What is the slope of the line that passes through the points (-10, 4)(−10,4) and (-10, 8) ?(−10,8)? Write your answer in simplest form.

undefined

Step-by-step explanation:

We can find the slope using two points

m = (y2-y1)/(x2-x1)

   = ( 8-4)/(-10 - -10)

   = ( 8-4)/(-10 +10)

   = 4/0

Since we are dividing by zero, the slope is undefined

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

a
