22 points anwser ASAP please Which of the following would graph a line with a slope of zero?

a
y = 2x - 3
b
y = 3
c
x = 3
d
3x +4y = 0

y=3

Step-by-step explanation:

For a line with a slope of 0 the y value never changes so the only answer where no change occurs to the y value is b.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
