Though this problem doesn't give instructions from working several of these i'm pretty sure what the instructions are and that would be to find the slope of the second line between the two points that are given so what we need to do is find out what f of two let's go to the first one we need to know f of two and f of five so when i put that in there, that's going to be eight plus seven is 15 and this is going to be 27 so now to find the slope i'm going to take 27 minus 15 and over 5 minus 2.
00:33
So it's going to be a 3 in the denominator.
00:35
That's going to be a 12 in the numerator for a slope of 4, which makes sense because it's linear, and we're talking about a slope of 4.
00:43
Now we're going to go here, f of 3, and then f of 3 .5.
00:48
So we're going to go 3 squared plus 6 plus 1.
00:52
That's going to be 16.
00:54
Let me see what 3 .5 is going to be.
00:56
That one's not quite as straightforward.
00:57
So i can go 3 .5 squared plus 3 .5 plus 1.
01:06
That's going to have a total of 16 .75.
01:09
So my slope will be 16 .75 minus 16 over 3 .5 minus 3, which is going to be 0 .75 over 0 .5.

Let's see what that's going to be...
