Plz help with slope question

C. (4, 8)

Step-by-step explanation:

→Plug in y = 2x into y = x + 4, like so:

y = x + 4

2x = x + 4

→Subtract x from both sides:

x = 4

→Now plug in 4 for x into one of the equations (doesn't matter which one):

y = 2x

y = 2(4)

y = 8

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

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
