The nation of Ectenia has 80 competitive apple orchards, which sell apples at the world price of $2 per apple. Q = 80L−L2 & MPL = 80−2L Suppose the world price of apples doubles to $4 per apple. Ectenia has 1,200 workers who supply their labor inelastically. The equilibrium wage is $ per worker per day. Each orchard hires workers and makes a profit of $ per day. (Note: Assume that wages are the firm's only costs.)

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up
