B
This is because they have the same slope and the same y-intercept.
Rearrange the 2nd equation and you'll get the exact same equation as the first one.

What type of system of linear equations is this? 

y = –5x – 4
y=1/2x+3

A.
consistent and independent
B.
consistent and dependent
C.
inconsistent
D.
independent and inconsistent

anonymous · Answer

This would be A
Cause they have different slopes and different y-intercept. It wouldn't be dependent, since both its slope and y-intercepts are different. They are consistent, as they do not possess the same slope, and is therefore independent.
