How to write expressions

To write an expression, you need operators such as -,+,or *. You will also require numbers, or in algebraic cases, variables. Two expressions that equal each other are considered equations. Know that expressions do not have equal signs, this is what separates them from a standard equation.

Some examples of expressions:

2 + 5

3 - 2

10 + 4

Some examples of equations

2 + 3 = 4 + 1

9 - 3 = 5 +1

2 * 10 = 5 + 15

(or just give brainliest)

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:

x equals 1
