Linear Relationships in Business Context

The video tutorial explains how to solve a word problem involving a linear relationship between the number of shirts sold and the price charged per shirt. It guides viewers through formulating a linear equation in the form P = MN + B, calculating the slope from given data points, finding the y-intercept, and writing the final equation. The tutorial uses a practical example to illustrate these concepts, making it easier for students to understand and apply the method in similar problems.

What type of relationship does the clothing business find between the number of shirts sold and the price per shirt?

• Quadratic

• Logarithmic

• Linear

• Exponential

In the equation P = MN + B, what does the variable 'P' represent?

• Y-intercept

• Price per shirt

• Slope

• Number of shirts

What are the two data points identified from the historical data?

• (1000, $40) and (4000, $13)

• (1000, $13) and (4000, $40)

• (1500, $30) and (3000, $15)

• (500, $20) and (2000, $10)

How is the slope (M) calculated from the two data points?

• By multiplying the prices and dividing by the number of shirts

• By subtracting the prices and dividing by the difference in the number of shirts

• By adding the number of shirts and dividing by the prices

• By adding the prices and dividing by the number of shirts

What is the calculated slope (M) for the linear equation?

• -0.009

• -0.027

• 0.009

• 0.027

Which point is used to find the y-intercept (B) in the equation?

• (3000, $20)

• (2000, $25)

• (4000, $13)

• (1000, $40)

What is the value of the y-intercept (B) in the final equation?

• 40

• 9

• 13

• 49

What is the final linear equation derived from the problem?

• P = 0.009N + 49

• P = -0.009N + 49

• P = 0.027N + 40

• P = -0.027N + 13

Why is it important to use the correct variables in the final equation?

• To ensure the equation is in standard form

• To match the variables given in the problem

• To make the equation easier to solve

• To avoid confusion with other equations
