Explanation Given information: N ( 1000 ) = 10 , 000 and N ( 1500 ) = 7 , 500 Formula used: Calculation: Need to find the change Δ N in the number of computers sold if the price is increased Δ P = 100 dollars. First calculate the value of N ( P ) if N ( 1000 ) = 10 , 000 and N ( 1500 ) = 7 , 500 Slope of the line passing through the points ( x 1 , y 1 ) and ( x 2 , y 2 ) is given by m = y 2 − y 1 x 2 − x 1 Let us take ( x 1 , y 1 ) = ( 1500 , 7500 ) and ( x 2 , y 2 ) = ( 1000 , 10 , 000 ) Substituting the values in slope formula. m = y 2 − y 1 x 2 − x 1 = 10 , 000 − 7 , 500 1000 − 1500 Replacing the values = 2500 − 500 Simplify = − 25 5 �
