Front

What is the Slope-Intercept Form of a linear equation?

Back

Front

How do you find the slope of a line given its graph?

Back

You need to identify 2 points on the line and use the formula: Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of a line?

Back

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

What is the definition of Standard Form for a linear equation?

Back

Front

How can you convert from Slope-Intercept Form to Standard Form?

Back

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The formula is: Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables.

Front

What is the y-intercept for the equation of a line that passes through the point (-1,5) and has a slope of 5?

Back

The y-intercept is 10.
