Question

There’s two lines, one with a slope of -2 and another with a slope of 2. Are they perpendicular?

Please help! :)

Answer 1

No they are not perpendicular

Step-by-step explanation:

for two lines to be perpendicular, the slopes have to opposite signs AND reciprocals of each other. So the slope of the first line would have to be -1/2 or the slope of the second line would have to be 1/2 for the two lines to be perpendicular
