Look at the table of values below.
x y
1 -1
2 -3
3 -5
4 -7
which equation is represented by the table?
y = 1 − 2x
y = -x − 1
y = x − 2
y = 2x − 1

Step-by-step explanation:

If you observe the given table, you would find that as x-values increase by one, y-values decrease by 2. This ratio of change can be found as the following,

The ratio of change is -2, which means the function is decreasing, beacuse its slope is negative.

Now, we can use the slope, one point and the point-slope formula, to find the equation that models those values

Therefore, ther right answer is the first choice.

i got 10.28 but that rounds up to 10.3

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
