Step-by-step explanation:
A) d = a2-a1 = 5-9 = - 4

Answer:
Step-by-step explanation:
y = 9 - X is a linear function; x is to the first power.
y = x2 + 1 does NOT represent a linear function; it's a quadratic function.
o
y=x² + 5 does NOT represent a linear function; it's a quadratic function.
D)
y = [xl - 9 does NOT represent a linear function; it's an absolute value function. This function has two halves, each of which is a linear function.
But the best answer here is that y = 9 - X is a linear function; x is to the first power.
