1) Which statement about 5y = 2x is true?

A) The equation represents a direction variation whose consent of variations is 5/2.

B) The equation represents a direct variation whose consent of variations is 2/5.


C) The equation does not represent a direction variation.


D) The equation does not represent a line through the origin.


2) What is the equation of the graph of y = |x| shifted 3 units up?

A) y = |x| – 3

B) y = |x| + 3

C) y = |x + 3|

D) y = |x – 3|


3) Two parallel lines form an inconsistent system of equations that has no solution.

True
or
False


Answer all and Show or Explain your answer :)

Respuesta :

1) B you can divide both sides of the equation by 5 and it will be of the form y = kx which is direct variation

2) B f(x) + k is a vertical shift up k units

3) True Because parallel lines have the same slope and different y - intercepts they do not touch thus called inconsistent.  Since they do not touch they will not have a solution.
