Answer:

If both equations have the same slope, they are said to be parallel.

If an equation is the reciprocal of another equation (meaning flipped denominator and numerator as well as flipped +/- sign) they are said to be Perpendicular.

Hope it helps!

Parallel lines will have the same slope! Perpendicular lines have opposite reciprocal slopes (opposite signs and reciprocal)

y = mx + b where m is the slope

The first and last equations have 2 as their m value and therefore are PARALLEL

Since the second equation has -1/2 which is the opposite reciprocal of 2, it’s PERPENDICULAR to the other two lines :)

The number would be greater. if you think about normal multiplication, when you multiply a number by 1 the number stays the same, but when you multiple the number by less then one, i.e. a fraction you get a fraction of what you had. while a number greater then one, i.e. 2, the number increases. so 1.23 is greater then one so it would increase
