A1 Semester 1 exam review

Front

What is the difference between continuous and discrete data?

Back

Continuous data can take any value within a range (e.g., weight, height), while discrete data can only take specific values (e.g., number of goals scored).

Front

What type of data is represented by the number of goals scored in a game?

Back

Discrete data.

Front

What type of data is represented by the weight of a whale?

Back

Continuous data.

Front

What is the y-intercept of the equation 2x - 5y = 35?

Back

(0, -7).

Front

What is the formula for standard form of a linear equation?

Back

Ax + By = C.

Front

What does the slope (m) represent in the equation y = mx + b?

Back

The slope represents the rate of change of y with respect to x.

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 meaning of the term 'rise' in the context of slope?

Back

Rise refers to the change in the y-coordinate between two points.

Front

What is the meaning of the term 'run' in the context of slope?

Back

Run refers to the change in the x-coordinate between two points.

Front

What is a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.
