Aline has a slope of -4/5. which ordered pairs could be points on a line that is perpendicular to this line? select two options. a - (–2, 0) and (2, 5) b - (–4, 5) and (4, –5) c - (–3, 4) and (2, 0) d - (1, –1) and (6, –5) e - (2, –1) and (10, 9)

A and E

Step-by-step explanation:

A line has a slope of -4/5, then a perpendicular line has a slope 5/4, because

Find the slopes of the lines in all options:

A. True

B. False

C. False

D. False

E. True

the correct answer is 5

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
