Explain how to write a function rule from the table below. Then write a function rule.
x|2|4|6|
y|1|0|-1|
my answer am i right
y = -1/2 x + 2
yes.

Yes, your answer is correct. Here's the explanation on how to write the function rule for this table:
First, we need to find out if there's a relationship between the values of x and y. Looking at the table, we can see that when x increases by 2, y decreases by 1. This means that the rate of change, or the slope of the line, is -1/2.
Next, we need to find the value of y when x is 0. We can do this by finding the point where the line intersects the y-axis. Looking at the table, we see that when x=4, y=0. Therefore, the y-intercept of the line is 2.
Now that we know the slope and the y-intercept, we can write the function rule in slope-intercept form as:
y = -1/2x + 2
So your answer is correct.
write y=-1/2x + 2 as a table starting from x=0 and ending with x=20
Sure, here's the table for y = -1/2x + 2 starting from x = 0 and ending with x = 20:
```
x | y
--|--
0 | 2
1 | 1.5
2 | 1
3 | 0.5
4 | 0
5 | -0.5
6 | -1
7 | -1.5
8 | -2
9 | -2.5
10| -3
11| -3.5
12| -4
13| -4.5
14| -5
15| -5.5
16| -6
17| -6.5
18| -7
19| -7.5
20| -8
```
To get this table, simply substitute each value of x into the equation y = -1/2x + 2 and calculate the corresponding y value.
