Interpreting Slope and y-Intercept

Front

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

Back

The y-intercept is the value of y when x is 0, representing the starting point of the line on the y-axis.

How do you interpret the slope of a linear equation?

Back

The slope represents the rate of change of y with respect to x, indicating how much y increases or decreases for each unit increase in x.

How can you determine if a line is increasing or decreasing from its slope?

Back

If the slope is positive, the line is increasing; if the slope is negative, the line is decreasing.

Front

How do you find the slope between two points on a graph?

Back

The slope is calculated using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

What does it mean if the slope of a line is zero?

Back

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

In the context of savings, how can the slope of a savings equation be interpreted?

Back

The slope indicates the amount saved per time period, showing how savings grow over time.

Front

What does the y-intercept represent in a real-world scenario, such as a savings account?

Back

The y-intercept represents the initial amount saved before any additional contributions are made.
