I think y is always 3 less than x. So for the first blank it would be 3 less than -1, that is -4. That makes the second blank -3. The third -8. And the last, -5.
The equation might be x-3=y
I might be wrong, please tell me if this is correct.
Answer:
The question and choices are cut off, could you repost it?
Step-by-step explanation:
There are three 'x's on the 3/4 spot, so you know that there are three 3/4 inch buttons.
To find how long they are lined up, you add them.
3/4 + 3/4 + 3/4 = 9/4
9/4 as a mixed number is 2 1/4.
Good luck!
Answer: f(2) is 3.
Step-by-step explanation:
f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

[One could also determine the equation for the line. Provided below.]
The slope is -(1/2) and the y-intercept is 4:
y = -(1/2)x + 4
For x=2,
y = -(1/2)*(2) + 4
y = 3
y(2) = 3
