Finding the Equation of a Line Using TI-Nspire

The video tutorial guides viewers through solving a digital exam question using a TI Inspire calculator. It involves finding the equation of a line given two points. The process includes setting up a new document, entering coordinates, and testing various functions to identify the correct equation that passes through the given points. The correct answer is determined to be option D.

What is the first step in solving the digital exam question using the TI-Nspire?

• Create a new document and add a graphs page

• Add a calculator page

• Add a spreadsheet page

• Open an existing document

Which letter do you type to choose the 'point by coordinates' option?

• P

• B

• C

• A

What are the coordinates of the first point entered?

• 6 and -50

• -5 and 4

• -2 and 70

• 3 and 40

What is the second coordinate entered into the TI-Nspire?

• 6 and -50

• -2 and 70

• 3 and 40

• -5 and 4

What should you do after entering both coordinates?

• Close the graph page

• Re-enter the coordinates

• Hit tab to type in the functions

• Save the document

Which function correctly goes through the given coordinates?

• -5x + 40

• 3x + 4

• -5x + 4

• 3x + 40

What is the correct answer option for the equation of the line?

• Option D

• Option C

• Option B

• Option A
