STEM FINAL EXAM REVIEW

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

Calculate 50% of 1800.

Back

900

Front

What is one reason the world population is increasing?

Back

The birth rate is higher than the death rate.

Front

What does a horizontal line on a graph represent?

Back

Not moving (constant position).

Front

What does a population pyramid showing a wide base indicate?

Back

Rapid growth in population.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the formula to calculate percentage?

Back

Percentage = (Part / Whole) x 100.

Front

What does a steep slope indicate on a graph?

Back

A steep slope indicates a rapid change in the value of y with respect to x.

Front

What is the significance of a population decrease in a population pyramid?

Back

It indicates that the number of deaths exceeds the number of births.

Front

What does it mean if a graph shows acceleration?

Back

It means that the speed of the object is changing over time.
