What is the slope of the line passing through point two, fourteen and point three, twenty-two.
00:00:09.530 --> 00:00:12.540
To solve this problem, weβll need the slope formula.
00:00:14.590 --> 00:00:20.310
The slope formula being the change in π¦ over the change in π₯.
00:00:22.060 --> 00:00:29.070
Another way to write it, π¦ two minus π¦ one over π₯ two minus π₯ one.
00:00:30.700 --> 00:00:33.250
So letβs use this formula and find the slope.
00:00:34.740 --> 00:00:43.940
Weβre given these two points, and we wanna label them as π₯ one, π¦ one; π₯ two, π¦ two.
00:00:45.520 --> 00:00:49.040
Now we wanna plug in our values into the formula.
00:00:50.400 --> 00:01:04.110
Weβll substitute the value twenty-two for π¦ two, fourteen for π¦ one, three for π₯ two, and two for π₯ one.
00:01:05.530 --> 00:01:06.940
Now I need to subtract.
00:01:07.110 --> 00:01:10.950
Twenty-two minus fourteen equals eight.
00:01:11.570 --> 00:01:14.820
Three minus two equals one.
00:01:16.270 --> 00:01:21.800
The slope of the line that passes through two, fourteen and three, twenty-two equals eight.
