Week 12 FLASHCARD

Front

What is the rate of change of temperature with respect to altitude in the Earth's atmosphere?

Back

The rate of change of temperature with respect to altitude is -6.5˚C/km.

Front

How do you calculate the slope of a linear function given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope and y-intercept of the linear function g that passes through the points (-7, -4) and (7, 6)?

Back

Front

What does a positive slope indicate about a linear relationship?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What is the definition of causation in a relationship?

Back

Causation means that one event is the result of the occurrence of another event.

Front

Which situation best illustrates causation?

Back

The amount of time a cell phone is used affects the charge of its battery.

Front

What is the rate of change of y with respect to x if the values in a table show a linear relationship?

Back

The rate of change is the difference in y-values divided by the difference in x-values.

Front

What is the solution set of the inequality 8x + 16y > 32?

Back

An example of an ordered pair in the solution set is (-3, 5).

Front

How do you determine if an ordered pair is a solution to an inequality?

Back

Substitute the x and y values into the inequality and check if the statement is true.

Front

What is the significance of the y-intercept in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.
