Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

y-intercept (0, 5)

Point (1, 2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{2-5}{1-0}$
Subtract: $m=\frac{-3}{1}$
Divide: $m=-3$

Step 3: Write Equation

Plug in variables into the general form.

y = -3x + 5

The graph of f(x) = (0.5) is replaced by the graph of g(x) = (0.5)x - k. If g(x) is obtained by shifting f(x) down by 3 units, t

cricket20 [7]

Recall that the the vertical shifting of functions is associated with the numerical value that is added to the original one. A possitive value k will shift the function k units up, and a negativa value (or subtracting k) will move it vertically down k units.

If I understand correctly, you forgot to type an "x"in the original function f(x), which should read:

f(x) = 0.5 x

Correct?

The new graph is g(x) = 0.5 x - k which is obtained by shifting the original f(x) DOWN by 3 units.

In order to shift the graph of f(x) DOWN three units, we need to SUBTRACT 3 from f(x), leading to : 0.5 x - 3

Therefore, the value of "k"in the given g(x) = 0.5 x - k must be 3.

which agrees with the last option in your list (option D)
