5) The graph of the parent linear function f(x) = x is shown in black on the coordinate grid. Write the function that represents this function with the indicated parameter changes. Slope (m) increased, y-intercept (b) unchanged.
Slope (m) decreased, y-intercept (b) unchanged.
Slope (m) unchanged, y-intercept (b) increased.
Slope (m) unchanged, y-intercept (b) decreased.

(m) increased, (b) unchanged.     g(x)

(m) decreased, (b) unchanged.   m(x)

(m) unchanged, (b) increased.      h(x)

(m) unchanged, (b) decreased.    n(x)

f(x): m = -1/2  b = 2

g(x): m = 1/3  b = -3

h(x): m = 2  b = 0

The total area:

12 units²

Step-by-step explanation:

There are three parts on this shape:

1 big right triangle

1 rectangle

1 small right triangle

area = (4*4)/2 = 16/2 = 8units²

area = 2*1 = 2units²

area = (2*2)/2 = 2units²

8+2+2 = 12 units²
