SOLUTION: I need help understanding the following: If (-1,-4) is a point on the graph of y=f(x), what point do you know is on the graph of y=f(1/2x)? Would the answer be (-1/2,-2) si

Question 168036: I need help understanding the following:
If (-1,-4) is a point on the graph of y=f(x), what point do you know is on the graph of y=f(1/2x)?
Would the answer be (-1/2,-2) since it is 1/2 of (-1,-4)?

We'll see shortly:
At points (-1,-4), and consider other points (0,0):

, "m"
Thru points (-1,-4):
, slope intercept form

, y-intercept=0:
Then, the line eqn follows:
-->(y)=4x ---> points (-1,-4)
If (y)=(1/2)(x), then,
--->(y)=(1/2)x ----> points (-1,-1/2), ANSWER
Thank you,
