How do you calculate average rate of change?

• Subtract the high minus the low

• Add up all the x values and all the y values and divide by the number of values.

• Create a new table with only the low value of the interval and the high value of the interval. Then calculate slope.

• Add up only the y values and divide by the number of values.

How do you determine if a graph shows a strong linear correlation between two variables?

• If the points are randomly scattered all over, there is a strong correlation.

• If the points are roughly arranged in a line, there is a strong correlation.

• There can only be a strong correlation if the points perfectly form a line.

• If the points never overlap, there's a strong correlation.

When solving an *inequality*, what should you do?

• Solve like a normal equation with no differences.

• Solve like a normal equation but flip the inequality when multiplying or dividing by a negative.

• Plug in random values of x and see what happens.

• Solve like a normal equation by flip the inequality when you add or subtract a negative number.
