Given the following system of equations:
−4x + 8y = 16
2x + 4y = 8
what action was completed to create this new equivalent system of equations?
−2x + 4y = 8
2x + 4y = 8
a. multiply the second equation, 2x + 4y = 8, by −1.
b. multiply the first equation, −4x + 8y = 16, by −1.
c. divide the second equation, 2x + 4y = 8, by 2.
d. divide the first equation, −4x + 8y = 16, by 2.

  D.Divide the first equation, −4x + 8y = 16, by 2.

Step-by-step explanation:

All you have to do is look at the effect of the proposed action on the constant on the right to tell which answer choices are incorrect.

D.Divide the first equation, −4x + 8y = 16, by 2.

Step-by-step explanation:

−4x + 8y = 16

2x + 4y = 8

Take the first equation and divide it by 2

−4x/2 + 8y/2 = 16/2

-2x + 4y = 8

i believe that the slope of the line is -5

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
