Which graph represents a function with direct variation? A coordinate grid with a line passing through (0, 1) and (1, 1)

A coordinate grid with a line passing through (negative 2, 1), (0, 0) and (2, negative 1)

A coordinate grid with a line passing through (negative 3, negative 3), (0, negative 2) and (3, negative 1)

A coordinate grid with a line passing through (negative 2, negative 2), (0, 1) and (2, 4)

**The anwser is b because it represents a function with a direct variation because of the negative 2**

Step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
