Answer:
y = -2x - 5
Step-by-step explanation:
<u>1) Find the slope of the line.</u>
The slope of the original line is the same as the slope of the parallel line.
Slope formula:

In this case you can choose any 2 set of points on the table.
=
=
= -2
So the slope of the line is -2
<u>2) Use the point-slope formula to find the equation of the line.</u>
Point-slope formula:

Now plug in the point (0, -5) and the slope -2 into the equation.
y - (-5) = -2(x - 0)
y + 5 = -2(x - 0)
To solve the equation first apply the distributive property.
y + 5 = -2x + 0
y + 5 = -2x
Next, subtract 5 from sides.
y = -2x - 5
You know have your equation in point-slope form!
700x + 375(27 - x) = 15000
Solve for x

Answer:
B shows a translation of three units to the right
Let the number of hamburgers sold be "h" and the number of cheeseburgers be "2h" as it was two time as the humbugers .form equation frome it '2h+h=387".comp the like terms which gives you 3h=387 divide each side by 3 which gives you h=129 which is equal to the number hambyrgers .multiply 129 by 2 to get the number of cheeseburgers which is 258
