A company has a manufacturing plant that is producing quality pairs of pants.
00:05
They find that in order to produce 220 pairs of pants in a month, $220 pairs cost $7 ,920.
00:14
To produce 340 pairs, it costs $11 ,040.
00:18
So we're going to find a linear function, y equals mx plus b.
00:22
And x is going to be the number of pants and y is the monthly cost.
00:27
The other thing that's going to help me here is to find m using my slope formula.
00:31
So for the y values, we're going to use the cost in the two different months.
00:37
So we got 11 ,040.
00:39
I'll use that one, minus 7 ,920.
00:43
And then i'm going to subtract their corresponding months.
00:47
Or sorry, corresponding pairs of pants.
00:49
So that's 340 for that month, minus the 220.
00:54
So for my slope, i'm going to get 3 ,120, divided by 120...
