Okay, for this question, you are trying to figure out which other point goes with line n.
00:07
We know that line m and n are parallel, and that's important because parallel lines have the same slope.
00:26
So what we can do is find the slope for line m and then figure out which of those points would give us the same slope for line n.
00:35
And the slope formula looks like this.
00:40
M equals y2 minus y1 over x2 minus x1.
00:49
So for line m, we have our coordinates.
00:53
We can call this one x1 and y1, and we'll call this one x2 and y2.
00:58
And if we substitute into our formula to find the slope, we'll have negative 6 minus 2 over 1 minus negative 5.
01:11
So negative 6 minus 2 is negative 8.
01:14
1 minus negative 5, that minus a negative is going to turn into addition.
01:20
So that's 6.
01:22
And i can simplify negative 8 over 6 to be negative 4 over 3, because those are both divisible by 2.
01:32
So if we go down your list, your first option to go with line n is the coordinate it six negative three.
01:41
So let's see if six negative three will work.
01:46
We're going to plug into that same slope formula...
