Question

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

Answer 1

do you know what each one means

Answer 2

solve both for y.

then graph the two functions together.

if they ever touch at all or many times they are consistent.

if they touch only once they are consistent and independent.

if they turn out to be the same line they are consistent and dependent.

If they are parallel lines then they never touch and are inconsistent.

Answer 3

therefore it is c.inconsistent

Answer 4
