Question 119686: In planning for a new item, a manufacturer assumes that the number of items produced x and the cost in dollars C of producing these items are related by a linear equation. Projections are that 100 items will cost $10,000 to produce and that 300 items will cost $22,000 to produce. Find the equation that relates C and x.
Thanks

Plot on the y-axis on the x-axis
The equation, if linear, will be of the form
, is the slope.
I'm given 2 points on the line, they are:
P1(100, 10000)
P2(300,22000)
Now I need to find the slope, of the line
connecting these points
So far I have where is the y-intercept
The slope-intercept formula is:
or,replacing with ,
answer
check:
when ,
This is a new point, P3(0,4000}. Using this point, do I
still get ?
OK
