Bi-Weekly Practice Review Activity -11/21/2024

Front

What is an undefined slope in a graph?

Back

An undefined slope occurs in a vertical line where the change in x is zero, making the slope calculation (rise/run) impossible.

Front

How do you determine the line of best fit from a set of data points?

Back

The line of best fit minimizes the distance between the line and all data points, representing the trend of the data.

Front

What does the y-intercept represent in a linear equation?

Back

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

Front

What is the equation of a line in slope-intercept form?

Back

The equation is given by y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you predict future values using a line of best fit?

Back

You can substitute the future x-value into the line's equation to find the corresponding y-value.

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.

Front

What is the range of a relation in mathematics?

Back

The range is the set of all possible output values (y-values) that a function or relation can produce.

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the significance of the line of best fit in data analysis?

Back

The line of best fit helps to summarize the relationship between variables and make predictions.

Front

What does it mean if a graph has a horizontal line?

Back

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