Okay, so you want to find the seekin line through a certain point on a graph telling you how many gallons of water you've lost in a period of time.
00:16
And that's a function where right here you have time and right here you have volume.
00:28
Now, you're asked to find a seekin line and all that seekin line is it's the line from two points on a function.
00:40
Say this one right here to this one right here.
00:46
And we want to find the slope of this line right here.
00:51
In this graph, it's not true to form.
00:55
You're not giving the full function.
00:58
So we can just call this in general bat.
01:03
And so we want to find where where this one point, say right here, p15 ,500, where t right here, all of that is, is the time, and this right here itself is v of t.
01:32
Now we're given that we can find the slope of that sequent line by the quix.
01:39
Equation to 1500 over t minus 15.
01:49
Now we wanna find the slope when t equals five.
01:54
And we know that at t equals five, it has a corresponding volume in gallons of 4 ,140...
