What is the equation of a line, in general form, with a slope of -2 and a yintercept of 8? x+2y-8=02x+y-8 = 02x-y+ 8 = 0

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

We have the slope m = -2 and the y-intercept b = 8. Substitute:

The general form of an equation of a line:

Convert:

             add 2x to both sides

             subtract 8 from both sides

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!
