Eliminate the parameter. x=t-3, y= 2/t+5

To get the system of equations in terms of x and y, solve for any other parameters and substitute back into the other equations.

y=2/x+8

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
