Answer:
slope: -1/2
y-intercept: -2
Step-by-step explanation:
f(x) = mx+b
m is slope
b is the y-intercept
so
if f(x) = -1/2x - 2
then
the slope or m is -1/2
and the y-intercept or b is -2

Answer:
C.
Step-by-step explanation:
So, here's what you need to remember:
If we have a function <em>f(x)</em> and a factor <em>k</em>:
<em>k(f(x)) </em>will be a vertical stretch if k is greater than 1, and a vertical compression if k is greater than zero but less than 1.
<em>f(kx) </em>will be a horizontal compression if k is greater than 1, and a horizontal stretch if k is greater than zero but less than 1.
We are multiplying 0.5 to the function. In other words: 0.5f(x).
This is outside the function, so it's vertical.
0.5 is less than 1, so this would be a vertical compression
