Find the distance between −340 and 207 on the number line.

547

Step-by-step explanation:

To find the difference between the 2 numbers, subtract -340 from 207:

207 - (-340)

Subtracting a negative number will change to adding a positive number:

207 + 340

= 547

So, the distance is 547

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
