Question

The table represents a linear function.
a) -8
b) -4
c) 2
d) 5

Answer 1

b. -4

Explanation:

Every time one x value increases the y value decreases by 4. In the x values shown the number that should come after -4 is -3 so the y values -2 and -2 that are 8 units apart should be halved and be -4. This function maintains a constant rate of change throughout the function.
