Find the Slope And Y Intercept
PLEASE HELP

The y-intercept is -2

the slope is 2.5/1 or 2.5

Explantation:

The slope formula is m=y2-y1/x2-x1

we can use the points (1,0.5) and (0,-2)  (i got these points from the graph)

m=-2-0.5/0-1

m=2.5 or 2.5/1

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.
