4. Determine the following for the equation y = vx – 1.

this isnt the answer but it helps solve the equation so here is a little explanation

Step-by-step explanation:

Cost Equation

-Is a mathematical equation for a straight line, to predict total cost.

-Total cost = total variable cost + total fixed cost or Y = vx + f

-Y = total mixed cost

v = variable cost per unit of activity

x = volume of activity

f = fixed cost over a given period of time

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
