How do you interpret the slope in a real-world context?

Back

The slope indicates how much the dependent variable changes for each unit increase in the independent variable.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

If a line has a negative slope, what does that indicate about the relationship between x and y?

Back

A negative slope indicates that as x increases, y decreases.

What does the y-intercept tell you in a real-world scenario?

Back

The y-intercept indicates the starting value of the dependent variable when the independent variable is zero.

In the equation y = 3x + 10, what does the slope of 3 mean?

Back

It means that for every additional unit increase in x, y increases by 3.

How can you find the slope from two points on a line?

Back

The slope can be calculated using the formula (y2 - y1) / (x2 - x1).
