Answer:
This is pretty simple
Step-by-step explanation:
So the only thing you need to know about negatives and positives is that if your multiplying or dividing a number with 1 negative in the expreession/equation The answer will always result in a negative. If its 2 negatives its always positive. Thats all you need to know and then just solve it from there.
The correct answers are :
y=-1/2x+5 is parallel.
-2x+y=-4 is perpendicular.
-x+2y=2 is neither.
x+2y=2 is parallel.
<h3>What are parallel lines and perpendicular lines ?</h3>
It is argued that two non-vertical lines in the same plane that have the same slope are parallel.
In terms of geometry, parallel lines are two separate lines that never cross each other and are located in the same plane. They may be vertical or horizontal. Examples of parallel lines can be found all around us on railroad tracks, in lines of notebooks, and at zebra crossings in daily life. It is impossible for two parallel lines to cross. Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane.
Perpendicular lines are two different lines that cross at a right angle of 90 degrees.

Answer:
No, the simplification is not done correctly. When multiplying
we should get -6 instead of -9.
the correct answer is 12k-8
