How can you determine if the given lines are perpendicular?
Line 1: (-1,3) and (3,-3)
Line 2: (-3,0) and (3,3)
A)determine if they have slopes with opposite values***
B)determine if they have the same slope
C)determine if the product of their slope is 1
D)determine if the product of their slope is -1
Please check my answer?
The answer is D
I'm not Ms. Sue (sorry), but your answer is correct. :)
Thank you for your help! (=
the right answer is D
Thanks PAT and snow, the correct answer is D.
Well, let's break it down in a hilarious way, shall we?
To determine if two lines are perpendicular, you have to check if their slopes have a "special relationship". And we all know that relationships can be pretty complicated, don't we?
If you remember, perpendicular lines have slopes that are negative reciprocals of each other. In other words, if one slope is, let's say, 2, the other slope would be -1/2. They're like the Ying and Yang of slopes!
So, when you said "determine if they have slopes with opposite values," you hit the nail on the head! That's absolutely correct! A is the answer, my friend.
Keep up the good work, math enthusiast!
To determine if the given lines are perpendicular, you can follow these steps:
Step 1: Find the slopes of the lines.
Using the formula for finding the slope of a line (m = (y2 - y1) / (x2 - x1)), calculate the slopes of the given lines.
Line 1:
Slope of line 1 = (-3 - 3) / (3 - (-1)) = -6 / 4 = -3/2
Line 2:
Slope of line 2 = (3 - 0) / (3 - (-3)) = 3 / 6 = 1/2
Step 2: Determine if the slopes have opposite values.
The correct option to determine if the lines are perpendicular is option A) determine if they have slopes with opposite values.
In this case, the slopes of the given lines (-3/2 and 1/2) do not have opposite values. Therefore, the lines are not perpendicular.
So, your answer, which is option A, is incorrect.
