d. one solution ******

Answer 1

How many solutions does this system have?
x-2y=2
y= -2x+5
a. infinitely many solutions ***
b. no solutions
c. two solutions
d. one solution

Answer 2

2y = x - 2
2y =-4x+ 10
different slopes so cross once, agree with you

Answer 3

Wrong the answer is one solution!!! I swear it

Answer 4

It is one solution. I got it wrong choosing infinitely many.

Answer 5

That is all

Answer 6

Parallel lines - infinitely many solutions
Parallel line have the same slope

Perpendicular lines - one solution
Perpendicular lines have different slopes

seems what thats was confusin yall.

Answer 7

I still don't understand could someone please explain how you figure out if they are perpendicular or parallel
