Finding the X Coordinate of the Intersection of Two Equations

This lesson teaches how to find the intersection of two equations by setting them equal. It covers the slope-intercept form, common misunderstandings in real-world problems, and provides an example with cell phone companies to illustrate the concept. The lesson concludes with a summary of the key points.

What does the 'M' represent in the slope-intercept form of an equation?

• The x-coordinate

• The y-intercept

• The slope

• The solution

In the context of equations, what is a solution?

• A value that makes an equation false

• A value that makes an equation true

• A method to graph equations

• A point where two lines intersect

What is a common mistake students make when identifying the slope and y-intercept in real-world problems?

• Using the slope as the y-intercept

• Confusing the x and y coordinates

• Using the rate of change as the y-intercept

• Using the initial value as the slope

In the example of the cell phone companies, what is the slope for the 'Textaway' company?

• $20.00 per month

• $0.40 per text

• $30.00 per month

• $0.20 per text

How many texts must be sent for the bills of 'Textaway' and 'It's Your Dime' to be equal?

• 30 texts

• 40 texts

• 50 texts

• 60 texts
