Line m passes through point (2,-7) and (4,-9). Line m is parallel to which line?

Mathematics

Reil [10]4 years ago
5 0

As the slope is -1, so any line that has the same slope is parallel.

<u>Solution:</u>

Given points (2, -7) and (4, -9) find the slope, m:

m = \frac{y - y_1}{x - x_1}

\Rightarrow m = \frac{-7 - (-9)}{2 - 4}

m = \frac{-7 + 9}{-2}

m = \frac{2}{-2}=-1

Any line that has the same slope is parallel.

Why do you think we have more protests in modern times than in earlier time periods?
Wittaler [7]
I think there are more protests in modern day times rather then in the earlier time periods, because people are now more aware of their rights, and how they influence the way their country is run. Also, nowadays most countries are democratic, meaning that everyone can express their opinions and people protest as a way of expressing their opinions about something.
