What is -2(x+y)+9=1 in standard form?

Step-by-step explanation:

ax+by=c

-2(x+y)+9=1

distrbute -2

-2x-2y+9=1

subtract 9 from each side

-2x-2y=-8

the x # cant be - so multiply each side by -

2x+2y=8

2? if not the correct answer you might need to provide more information

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
