If an indifference curve were horizontal ( assume X is measured on the horizontal axis and Y along the vertical axis) , this would mean that the consumer is saturated with (a) good X only, (b )good Y only (c ) both good X and Y or ( d) neither good X and Y.

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.

all options are correct a) b) c) and d)
