Question

WHO WANTS A MEDAL???!

Answer 1

for what?

Answer 2

Given that the value of b can never be equal to -1, determine if the equations are intersecting, parallel, or coincident.

x + y = ab
bx - y = a

Answer 3

Intersecting
Parallel
Coincident

Answer 4

coincident

Answer 5

How do you know?

Answer 6

i want a medal!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 7

wait what?
no?
it shouldn't be coincident

Answer 8

???

Answer 9

sorry it would be parallel

Answer 10

x + y = ab --> y = -x + ab
bx - y = a --> y = bx - a
^ so if b cannot be = -1
then they cannot be parallel
(since they would not have the same slopes)
and they have to be at least parallel to be coincident

Answer 11

gosh
people

explain your work o-o

Answer 12

I stand by what I said

it is Not parallel
AND it is Not coincident

Answer 13

thankyou @sleepyhead314
