$\bf (x-7)(x^2+3x-3)~\hfill \begin{array}{cll} x^2+3x-3\\ \times x\\ \cline{1-1} x^3+3x^2-3x \end{array}~~+~~ \begin{array}{cll} x^2+3x-3\\ \times -7\\ \cline{1-1} -7x^2-21x+21 \end{array}~\hfill \\\\[-0.35em] ~\dotfill\\\\ (x^3+3x^2-3x) +(-7x^2-21x+21)\implies x^3-4x^2-24x+21$

notice that all you do is simply multiply the terms of either one by the terms of the other sequentially, then add like-terms.

Mathematics

The slope of the line given is -5/3

Steeper:
y= -2x+7/3
y=-7/4x + 3/2

Less steep:
y=-8/7x + 4/7
y=-3/2x+1/2
y=-4/3x+2/3

Hope this is helpful!
