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
Write the equation for the graph with the vertex (-6,2) and focus (-7.25,2) a. (y-2)^2 = -5(x+6) b. (y+6)^2 = -5(x-2) c. (x+6)^2 = -5(y+2) d. (y-6)^2 = 5(x+6)
