Answer:
Linear function. It is actually a negative linear graph. for the products prices increases, there was a noticeable decrease in demand
slope y=-225/8x+19275/8
y=1987.5
y=1903.125
Explanation:
A consumer products company has collected some data relating monthly demand to the price of one of its products: 4. Price Demand $111100 2,100 $13 2,020 1,980 1,875 $19 What type of model would best represent these data?
Linear function. It is actually a negative linear graph. for the products prices increases, there was a noticeable decrease in demand
slope is
m=y2-y1/(x2-x1)
PICKING TWO POINTS
(11,2100) and (19,1875)
m=1875-2100/(19-11)
m=-225/8
as the slope
(11,2100). y=mx+b or
2100=-225/8 × 11+b,
solving for b: b=2100-(-225/8)(11).
b=19275/8.
(19,1875). y=mx+b or 1875=-225/8 × 19+b, or solving for b: b=1875-(-225/8)(19).
b=19275/8. is the intercept
y=mx+c is the equation of line graph
y=-225/8x+19275/8
when x=15
y=1987.5
when x=18, y=
-225/8(18)+19275/8
y=1903.125
