Exploring Slope and Rate of Change in Algebra 1

This video tutorial covers the concepts of slope and rate of change in algebra. It explains how to find the slope from a graph, two coordinates, and a table, and discusses the differences between positive, negative, zero, and undefined slopes. The tutorial also covers how to determine the rate of change from a story problem, using examples like bodybuilding and collecting Pez dispensers. The video emphasizes the importance of understanding slope as a foundation for further algebraic concepts.

What is the primary focus of this lesson?

• Understanding algebraic expressions

• Learning about slope and rate of change

• Solving quadratic equations

• Graphing linear inequalities

Which of the following best describes slope?

• The length of a line

• The steepness and direction of a line

• The width of a line

• The angle of a line

What does 'rise over run' refer to?

• The angle between two lines

• The total length of a line

• The distance between two points on a line

• The vertical and horizontal distance a line covers

What is the slope of a line that rises 2 feet and runs 18 feet?

• 18

• 9

• 2/18

• 1/9

How is a negative slope represented?

• A line that rises as it moves left to right

• A perfectly vertical line

• A line that falls as it moves left to right

• A perfectly flat line

What is the slope formula?

• m = x2 - x1 / y2 - y1

• m = y2 - y1 / x2 - x1

• m = x1 - x2 / y1 - y2

• m = y1 - y2 / x1 - x2

If given the points (2, 11) and (8, 35), what is the slope?

• 4

• 3

• 2

• 1

How do you find the slope from a table of values?

• By multiplying all the values

• By dividing all the values

• By finding the difference between y-values and x-values

• By adding all the values

In a story problem, what does the rate of change represent?

• The change in one variable relative to another

• The initial value of a variable

• The time taken to complete a task

• The total distance covered

Why is understanding slope important in algebra?

• It helps in solving quadratic equations

• It is the foundation for understanding linear relationships

• It simplifies complex numbers

• It is used in geometry
