3.) which equation represents the line that is parallel to y = 3 and passes through (-2,-8)?
a. x = -2
b. x = 3
c. y = -8
d. y = 3x − 2

D

Step-by-step explanation:

needs same gradient im guessing

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
