Question

The lines of the equations are parallel, perpendicular, or neither.

y = -x + 3
y = -x - 3

parallel
perpendicular
neither

Answer 1

Find the slopes

Answer 2

-x

Answer 3

The line is perpendicular if the slopes are reciprocals of each other

Answer 4

And opposite integers from each other

Answer 5

???

Answer 6

-x isn't a number, the slope is the number before the 'x'

Answer 7

-1

Answer 8

There is an invisible one there.. y = -1x + 3

Answer 9

Yes, correct, now what about the 2nd one?

Answer 10

-1

Answer 11

So let's say the slope is 1/3. For it to be perpendicular, the other slope has to be -3. Flipp the fraction 1/3 around to have 3/1 which is equal to 3, then change it to the opposite integer sign, a negative sign, so you would have -3

Answer 12

Yes, so the slopes are parallel.
