Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the y-value changes for a one-unit increase in the x-value.

What does the y-intercept indicate in a real-world context?

Back

In a real-world context, the y-intercept represents the initial value of the dependent variable when the independent variable is zero.

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept indicates the value of the independent variable when the dependent variable is zero, often representing a point of no effect or change.

Front

How do you graph a linear function?

Back

To graph a linear function, identify the y-intercept, plot it on the graph, use the slope to find another point, and draw a straight line through the points.

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

Back

Front

What does a positive slope indicate about a linear function?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing a direct relationship.
