each table represents a linear relationship. Use the slope formula to find the slope or rate change shown in each table.

Answer 1

1 2 3 4

Y 14 10 6 2

To find the slope, we use the formula:

slope = (change in Y) / (change in X)

For the first two points:

slope = (10-14) / (2-1) = -4 / 1 = -4

For the next two points:

slope = (6-10) / (3-2) = -4 /1 = -4

For the last two points:

slope = (2-6) / (4-3) = -4 / 1 = -4

Therefore, the rate of change for each table is -4.
