What is the equation of the line with m = 3 and b = 8.25?
a. y = 3x – 8.25
b. y = 3x 8.25
c. y = 3x 8.25
d. y = 3x 8.25

answer: none of these answers are correct only the second half is

step-by-step explanation:

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
