Eric sells shirts. it costs him $100 to buy all the shirts and $10, total, to print designs on them. eric sells each shirt for $4. so far he has sold 20 shirts. he uses the equation y = 4x - 110 to calculate his profit.

what is the constant in eric’s equation?
a) 4
b) -10
c) 20
d) -110

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
