Below are two different functions , f(x) and g(x) what can betwrmined about their slopes. f(x)=4x+2

Slope of the given function is 4.

Step-by-step explanation:

We have been given a function  F(x) =4x+2

We will compare the given equation by general equation which is: y= mx+c  where m is the slope of the line that is coefficient of x.

Here the coefficient of x in give function is 4 or m=4.

Hence, the slope of  given function is 4.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
