Unit 3 Review Linear Equations (Graded) Block 4

Front

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

Back

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive or negative).

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the value of y when x = 0. It is the point where the line crosses the y-axis.

Front

How do you interpret a positive slope?

Back

A positive slope indicates that as x increases, y also increases. This means there is a direct relationship between the two variables.

Front

How do you interpret a negative slope?

Back

A negative slope indicates that as x increases, y decreases. This means there is an inverse relationship between the two variables.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot. It shows the general direction of the data points.

Front

What does it mean if there is no relationship in a scatter plot?

Back

If there is no relationship in a scatter plot, it means that changes in one variable do not affect the other variable, and the points do not show any clear pattern.
