Which set of ordered pairs is made up of points on the graph of the function below?
y = -3x + 8
8
a. 

(-1,11), (0,8), (1,5), (2,2)

  b. 

(11,-1), (8,0), (5,1), (2,2)

  c. 

(11,-1), (8,0), (1,5), (2,2)

  d. 

(-1,11), (8,0), (1,5), (2,2)

its a straight line parallel to the time axis

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!
