Answer:
hgjjjjjjjjjjjjjjjjggggg
Step-by-step explanation:
hggggggggggggggggggjgjjj
The rate of change is the slope.
f(x) is the same as y...
f(x) = 3x + 9.....y = 3x + 9....and in y = mx + b form, the rate of change(slope) can be found in the m position.
y = mx + b
y = 3x + 9....so the slope or rate of change is 3...not 9...so answer is false
