Answers: 4, 3, 2
Each number gets its own box, and the values are entered in that exact order.
============================================================
Explanation:
x and y are placeholders for numbers.
If we replace x with -1, then we get
y = -x+3
y = -(x)+3
y = -(-1)+3 ... replace x with -1
y = 1+3
y = 4
This means that x = -1 leads to y = 4. So we'll write 4 underneath the "-1" in the y row.
------------------------
Similarly, if x = 0, then
y = -x+3
y = -0+3
y = 0+3
y = 3
Leading to 3 being the next item we input.
------------------------
Finally, if x = 1, we get this y value
y = -x+3
y = -1+3
y = 2
Which is the last value in the bottom row.
------------------------
The order of the y values in the bottom row is therefore: 4, 3, 2
This means the points (-1, 4), (0, 3), and (1, 2) are on the line y = -x+3.
Side note: The equation y = -x+3 has slope -1 and y intercept 3.
