What does a positive slope indicate about the relationship between two variables?

Back

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

Front

What does a negative slope indicate about the relationship between two variables?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If the slope of a line is 1, what does this imply about the change in y relative to x?

Back

If the slope is 1, it means that for every unit increase in x, y increases by the same amount.

What is the slope of the line represented by the equation y = 2x + 5?

Back

The slope of the line is 2, which means for every unit increase in x, y increases by 2.
