I solved this by hand first, then cymath, then Wolfram alpha. we all agree the solution to the equation involved is x=-3 however -3 is not a multiple of 6. if you plug it in you get a solution of 24 but I don't consider this to be a valid question.

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Given

6x + 10y = 8 ( subtract 6x from both sides )

10y = - 6x + 8 ( divide each term by 10 )

y = - \frac{6}{10} x + \frac{8}{10} = - \frac{3}{5} x 6 + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C

c) scale facot is 7.2/5 = 1.44

the square scale factor is 1.44^2 = 2.0736

times 20 by this to get the area

2.0737x 20 = 41.472 m²
