Question

Please answer this math question !! Multiple choice !! Thank u and I will give brianliest !!

Answer 1

Answer:

B

Step-by-step explanation:

Perpendicular lines have opposite-reciprocal slopes

So if I had a slope of 2, the perpendicular slope would be -1/2.

Or if I had a slope of -7, the reciprocal is -1/7 and the opposite would be 1/7.

Hope this helps!

Answer 2

Answer:

B

Step-by-step explanation:

Remember, perpendicular lines have NEGATIVE RECIPROCAL slopes! This means that a line with a slope of a/b's perpendicular line would be -b/a! You can see that in option B, the slopes of the lines are -7 and 1/7, which are negative reciprocals.

Let's take -7 and flip it, then change the sign:

-7 -> -7/1 -> -1/7 -> 1/7

We just confirmed that -7 and 1/7 are negative reciprocals! Therefore, two lines with these slopes are perpendicular.
