Solve the following system of equations {-2x+y=2, 3x-2y=4

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

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
