The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = 1/4 (x – 8). What is the slope-intercept form of the equation for this line?y = y = 1/4x - 12.x – 12y = y = 1/4x - 4.x – 4y = y = 1/4x + 2.x + 2y = y = 1/4x + 6.x + 6

Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in thousands of cartons) by the following equation.$ 625p^2 - x^2 =100$If 35000 cartons of eggs are available at the beginning of a certain week and the price is falling at the rate of 5¢/carton/week, at what rate is the supply changing? (Round your answer to the nearest whole number.) (Hint: To find the value of p when x = 35, solve the supply equation for p when x = 35.)___ cartons per week?
