X+y=5
2x + 2y = 10
Put into y=Mx+b

y = -x + 5

Step-by-step explanation:

Set both of them to y=mx+b so that you can set them equal to each other to solve for both x and y

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

graph of this function as shown below:

1 is c

2 is a

3 is a
