Y = -2.8x +69.4
Let y represent units of inventory, and x represent days since the last replenishment. We are given points (x, y) = (3, 61) and (13, 33). The line through these points can be described using the 2-point form of the equation of a line:
... y -y1 = (y2-y1)/(x2 -x1)(x -x1)
Filling in the given point values, we have ...
... y -61 = (33 -61)/(13 -3)(x -3)
Simplifying and adding 61, we get ...
... y = -2.8x +69.4
Okay so first plug this in
8-5
——
5-6
3/-1
-3
Slope= -3
y=-3x+b
Next, plug in one of the points to find b.
5=-3(6)+b
5=-18+b
+18 +18
—————
23=b
y=-3x+23
Hope this helps!!
The second one hopefully. I dk
