Front

What does the vertex of an absolute value function represent?

Back

The vertex represents the minimum or maximum point of the graph.

Front

How do you determine the line of best fit from a scatter plot?

Back

By drawing a line that best represents the trend of the data points.

Front

What is the effect of adding a constant to the absolute value function y = |x|?

Back

It shifts the graph vertically.

Front

What does the slope in the equation of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0.
