Y = mx + c where y = unit sold, c = selling price

60,000 = m * 210 + c                          (1)

130,000 = m *170 + c                        (2)

Subtract (2) – (1)

70,000 = - 40 *m 

m = -1750

Using (1), put m and find c,  60000 = - 1750 *210 + c

C = 165000

a) Line equation:  y = -1750 x + 427500
b) For selling price = x = $150, y = 165,000 units

Let x be the selling price($) per unit.
Let y be the number of units sold in 1000s).
Then, the linear relationship of price and sales represent as,
y=mx+c
where the slope of the equation is m and the y-interceptis c. !!
When the price x = 210, units soldy= 60:
Substitute 210 for x and 60 for y in the equation y = mx +c,
To get 60 = 210m+c.   .....  (1)
When the price x = 170, units sold = 130: 
Substitute 170 for x and 130 for y in the equation y = mx+c,
To get 130 = 170m+c........(2)
Subtract the equation (1) from the equation (2), to get
130-60 = (170m+c)-(210m+c)
70= -40m-70/40=m-7/4=m
Substitute the value of m in equation (1),to get
60 = 210m +c
60=210*-7/4+c
855/2=c
C=427.5
So, the equation that describes the relationship between the price and the units sold in 1000s is,
y = mx + c
y =-7/4x+427.5
=-1.75x+427.5
Therefore, the required equation is,y=-7/4x+427.5 or y = -1.75x + 427.5(b)
Selling price per unit = $150
Number of units sold in 1000s) is given by
y=-7/4x+427.5
Substitute x = 150 in the above equation, to calculate y.
y = -7/4x+427.5y=-7/4(150)+427.5
=330/2
= 165
So, the number of units expected to sell at a price of $ 150 per unit is 165000
Therefore, the required answer is 165000 units.
