To find the slope of these two points, we must use the formula m equals y2 minus y1 over x2 minus x1.
00:14
Remember in each ordered pair, x is the first number, and y is the second.
00:21
Now, since these are fractions, what we have to keep in mind is do they have common denominators? that makes our life so much easier.
00:28
So we're going to start with our ys.
00:29
We have negative three -fourths minus negative one -fourth.
00:37
They have a common denominator, so that's going to be easy math.
00:40
And then for our x values, we have different denominators.
00:44
We have two -thirds, and we have five -six.
00:47
So we can change two -thirds, so it becomes four -sixth.
00:52
And that way, we have a common denominator.
00:55
We just multiplied the top and bottom of two -thirds by two.
01:00
So now i'm going to plug that in.
01:03
So since we put negative three -fourths first, we're going to put five -six first in the bottom.
01:08
So five, six minus our new fraction of fourth -six.
01:14
Now, when we subtract a negative, remember that turns into adding.
01:20
So negative three -fourths plus one -fourth...
