Exploring Non-Proportional Tables

The video tutorial covers non-proportional relationships, focusing on how to derive equations from tables and graph them. It explains the equation y = mx + b, detailing the roles of slope (m) and y-intercept (b). The tutorial provides step-by-step guidance on finding these components from a table and graphing the resulting equation. It concludes with a practice problem and encourages students to seek help if needed.

What is the main focus of today's lesson?

• Understanding proportional relationships

• Exploring exponential functions

• Learning about non-proportional relationships

• Studying quadratic equations

In the equation y = mx + b, what does 'm' represent?

• Y-intercept

• Slope

• Variable

• Constant term

What is the y-intercept in the equation y = mx + b?

• The product of x and y

• The value of y when x is zero

• The value of x when y is zero

• The slope of the line

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

• By subtracting the x-values from the y-values

• By multiplying the x-values by the y-values

• By adding all the y-values

• By dividing the change in y by the change in x

What is the y-intercept if the equation is y = x - 2?

• 1

• -2

• 0

• 2

When graphing the equation y = x - 2, where does the line cross the y-axis?

• At y = 0

• At y = 1

• At y = -2

• At y = 2

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

• The line is vertical

• The line is horizontal

• The line descends as it moves to the right

• The line ascends as it moves to the right

In the example where Jesse began seven feet above sea level, what is the y-intercept?

• -0.2

• 0.2

• -7

• 7

How do you graph the equation y = -1/5x + 7?

• Start at y = 7 and go up 1, right 5

• Start at y = 7 and go down 1, right 5

• Start at y = -7 and go up 1, right 5

• Start at y = -7 and go down 1, right 5

What should you do if you don't understand a concept in the lesson?

• Guess the answer

• Ask your teacher for help

• Look it up online

• Ignore it and move on
