Find the slope of this line

undefined

Step-by-step explanation:

This is a vertical line.  Vertical lines have a slope of undefined

Checking:

m=( y2-y1)/(x2-x1)

   = (-5 - -2)/( 5-5)

   = (-5+2)/(0)

   -3/0

undefined

undefined

Step-by-step explanation:

the slope is 3 over 0 or 3/0 but that is mathematically not possible so it is considered undefined

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.
