3. Find the slope of points
(-2, 6) and (9,-2).

slope = - 4/11

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - 6 / 9 - (-2)

-4/11

understand that i don't know the answers

will someone answer his question

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.
