(-4,5)(-2,-3)
slope(m) = (y2 - y1) . (x2 - x1)
slope(m) = (-3-5) / (-2-(-4) = -8/2 = - 4
y = mx + b
slope(m) = -4
(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -4(-4) + b
5 = 16 + b
5 - 16 = b
-11 = b
equation is : y = -4x - 11
2 x 103 = 206, 8 x 105 is 840.
840 is roughly 4.08 times greater than 206.

F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
