Question

Point 1: Y -3, X- 1, Point 2: Y -4, X-2, Point 3: Y-12, X-3, Point 4: Y-15, X-4

Y is facts,
X is day number

Find the rate of change between day 4 and day 1.

A. 4 B. 12 C. 3 D. 15

Answer 1

To find the rate of change, we need to calculate the difference in Y-values and divide it by the difference in X-values.

Y-value difference: -15 - (-3) = -15 + 3 = -12
X-value difference: 4 - 1 = 3

Rate of change = Y-value difference / X-value difference
Rate of change = -12 / 3 = -4

Therefore, the rate of change between day 4 and day 1 is -4.
