Answer from: Quest

the formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

from a table we have

x_1=-4,\ y_1=7\\\\x_2=-2,\ y_2=5

substitute:

m=\dfrac{5-7}{-)}=\dfrac{-2}{2}=-1

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

answer: the function g(x) has the greatest slope.
The functions, f(x) and g(x) , are shown below. x f(x) -4 7 -2 5 0 3 2 1 4 -1 which function has the
