Your answer would be approximately 254.5 if you round since 9^2 times pie you would get such
A positive 3430. because two negatives that are being multiplied by eachother are automatically positive.
- Slope Formula:

So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
I think it's the second equation. I could be wrong but I think that's what it is
