Answer:

y = -x+6

Step-by-step explanation:

We can use the slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -1x+b

Substitute the point into the equation

-8 = -1*2 +b

-8 = -2+b

-8+2 = -2+b+2

-6 =b

y = -x+6

Step-by-step explanation:

we know that

To find out how much the guests ate, multiply the total amount of kg of mashed potatoes by the 4/12 fraction

$5(\frac{4}{12})=\frac{20}{12}\ kg$

convert to mixed number

$\frac{20}{12}=\frac{12}{12}+\frac{8}{12}=1\frac{8}{12}\ kg$

Answer:

Rectangle A is not a scale drawing.

Rectangle B is a scale drawing.

Step-by-step explanation:

A scale drawing involves ratios.

Rectangle A:

10cm is double the original 5cm giving us a 1 : 2 ratio.

However, 25cm is <em>not</em> double the original 20cm. This means that this rectangle is not to scale of the given rectangle.

Rectangle B:

10cm is double the original 5cm giving us a 1 : 2 ratio once again.

This time however, 40cm is double the original 20cm. This means that this rectangle is a scale drawing of the given rectangle.
