Front

Define 'slope' in the context of a linear equation.

Back

The slope is the rate of change of y with respect to x, represented as 'm' in the equation y=mx+b.

Front

What does a negative correlation in a scatter plot indicate?

Back

As one variable increases, the other variable decreases.

Front

What is the formula for the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you identify a scatter plot with no correlation?

Back

The points are scattered randomly without any discernible pattern.

Front

What does the term 'linear regression' refer to?

Back

A statistical method used to model the relationship between a dependent variable and one or more independent variables.
