Line r passes through points (5, 3) and (9, 8). Line s is perpendicular to r. What is the slope of line s?

The slope of the line would be 1.25!

Step-by-step explanation: I'll provide a screenshot of the graph I have made in a second! (:

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.
