Equals negative x minus 5.
00:05
The question asks you the graph using three points.
00:08
So basically you're going to pick three random x and plug into the equation and calculate for fx.
00:14
Then you have three points and you can do your graph.
00:17
So let's choose x equals three points, usually negative 1, 0, and positive 1.
00:26
So let's do it 1 .1.
00:28
So first of all, when x equals negative 1, so then fx, f -negedive 1 equals negative negative 1 minus 5.
00:38
So this is going to be 1 minus 5, which is negative 4.
00:43
So the first point is going to be x, negative 1, y, negative 4.
00:48
Second point, 0, f0.
00:52
Negative 0 minus 5 equals negative 5.
01:01
So the second point is 0 -9 -5.
01:06
Third point, x is positive 1.
01:08
So this is negative 1 minus 5.
01:12
It's negative 6.
01:13
So the third point is negative 1, negative 6...
