You want to determine the equational line through the points negative 6, negative 1, and 6, negative 4.
00:06
And i think a good thing to always do is to just quick sketch a graph of this just so you have an idea whether your answers are correct.
00:15
So the first point is negative 6, negative 1.
00:18
Negative 6, negative 1 would be a dot down here.
00:21
And then 6, negative 4 is going to be a dot down here.
00:25
So we can see that the slope should be negative.
00:28
Sorry, that's not so straight.
00:29
And we can approximate where that y -intercept is.
00:32
So let's find the slope first.
00:34
So the slope is the difference in the y's.
00:37
And it doesn't matter which way we subtract.
00:39
I'm going to go negative 4 minus negative 1 over the difference in the x's, 6 minus negative 6.
00:46
So we end up getting for the numerator a negative 3.
00:50
And in the denominator, we get 12...
