Question

0.4 Check whether the lines x+y=1 and 2x+y=x+2 are parallel or perpendicular.​

Answer 1

Answer:

So, we have I) x+y=1

ii) 2x+y=x+2, or, x+y=2

Now, for lines to be parallel we have

a1 = b1 ≠ c1

a2 b2 c2

Step-by-step explanation:

So from the equations we get

a1=1, b1=1, c1=1

a2=1, b2=1, c2=2

So, 1/1=1/1≠1/2

This fulfills the criteria of parallel lines, so they are parallel
