USE THE DATA TO ANSWER THE FOLLOWING QUESTIONS:

1. The bluestripe snapper (ta'ape) is an introduced species that is not native to the Islands. What would be the probability of catching this fish compared to the native lavender tang (mai'i'i)?



2. The mean biomass of the whitebar surgeonfish (maikoiko) is much higher than the mean biomass of the saddle wrasse (hinälea lauwili). Which fish would you be more likely to catch when you go fishing? Why?


3. What would be the mean biomass for all of the species combined?

Equations

Solve for X by keeping the equation in balance.

Slope Game

Zap the cockroaches by figuring out the equations of their straight paths! The goal is to keep moving up to the next level!!

If you have extra time, you can practice guessing the rule of linear functions.

Slope

Below is a graph that matches the equation shown.

Slope slider

Play around with adjusting the numbers and figure out how they effect the graph.

#1. When you change the number multiplied by x, how does that effect the graph?
What happens when it is negative?
What does the graph look like when it is zero?

#2. When you change the number added at the end of the equation, how does that effect the graph?
What happens when it is negative?
What does the graph look like when it is zero?
