Select the correct answer. What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?
O A. y = 3x + 4
OB. y= 3x - 14
O C. y= 3x - 4
OD. y = 3x + 12

A

Step-by-step explanation:

Put your information in the the point slope formula y-y1=m(x-x1)

This will give you y+5=3(x+3)

simplify

y+5=3x+9

Now subtract 5

y=3x+4

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
