Answer:
600
Step-by-step explanation:
10*-5=-50*-4=200*3=600
The answer is 600.
See attached graph.
The y-intercept is (0, 1), since the line is at that point when it intersects with the y-axis.
The common ratio is 1/4, since the y value multiplies by 1/4 for each unit on the x-axis.
The answer is 1 because 2^4=16 and 4^-2=0.0625 so if you multiply these together you get 1
2^4X4^-2
16X0.0625
=1
