ALGEBRA Semester 1 REVIEW

Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the relationship between height and weight based on a positive correlation?

Back

As height increases, weight also tends to increase.

Front

What defines a function in mathematics?

Back

A relation where each input has exactly one output.

Front

What type of correlation indicates that as one variable increases, the other decreases?

Back

Negative correlation.

Front

What is the slope of a horizontal line?

Back

0

Front

How do you determine if a table represents a function?

Back

Check if any input value is repeated.

Front

What does a positive correlation in a scatter plot indicate?

Back

Both variables increase together.

Front

What is the formula for calculating the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.

Front

What does it mean if a scatter plot shows no correlation?

Back

There is no discernible relationship between the two variables.

Front

What is the difference between a linear and a nonlinear function?

Back

A linear function creates a straight line when graphed, while a nonlinear function does not.
