The Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

The graph provided suggests the use of the points (3,-3) and (5,-3). The slope is:

The slope of the line is 0. It corresponds to a horizontal line

Answer:
6x^6y^8z^6
Step-by-step explanation:
(3x^3y^4z^4)(2x^3y^4z^2)
= 6x^(3+3) y^(4+4) z^(4+2)
= 6x^6y^8z^6
