Does anyone know how to do this!?!? If its correct ill mark u as the best answer choice!!?

I answered the two questions below and the two graphs:)

Step-by-step explanation:

7y−5x=14

Step 1: Add -7y to both sides.

−5x+7y+−7y=14+−7y

−5x=−7y+14

Step 2: Divide both sides by -5.

−5x

−5

=

−7y+14

−5

x=

7

5

y+

−14

5

y=−2x−1

Step 1: Flip the equation.

−2x−1=y

Step 2: Add 1 to both sides.

−2x−1+1=y+1

−2x=y+1

Step 3: Divide both sides by -2.

−2x

−2

=

y+1

−2

x=

−1

2

y+

−1

2

y=−2x−1

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
