Question

What type of system of linear equations is this?

y = –5x – 4

A.
consistent and independent
B.
consistent and dependent
C.
inconsistent
D.
independent and inconsistent

Answer 1

the other equation is missing

Answer 2

y=1/2x+3

Answer 3

what are the slopes of each equation?

Answer 4

1/2 and -5

Answer 5

good, so because the slopes are different, the two lines must intersect somewhere (unequal slopes means that the lines are NOT parallel)

Answer 6

what does that mean in terms of (in)consistent equations and (in)dependent equations?

Answer 7

I figured it out, thanks.

Answer 8

what did you get

Answer 9

Consistant and dependent.

Answer 10

close

Answer 11

if the two equations were dependent, then they would be the same equation, which would mean they would have to have the same slopes
