Question

X: -5, -4, -2, 2, 3

Y: -35, -28, -14, 14, 21
What is the scale factor?
A. 7
B. 8
C. 2
D. 1

Answer 1

The scale factor is 7.

Step-by-step explanation:

To find the scale factor, we can compare the corresponding values of X and Y. The ratio of the corresponding values is:
X: -5, -4, -2, 2, 3
Y: -35, -28, -14, 14, 21

Dividing the corresponding values, we get:
(-35)/(-5) = 7
(-28)/(-4) = 7
(-14)/(-2) = 7
(14)/(2) = 7
(21)/(3) = 7

Since the ratio is consistent for all pairs, the scale factor is 7, which is option A.
