Please review the video below to help refresh how to use the TI Nspire calculator to solve linear systems of equations.
Question 1
1.
What is the solution?
5x = 15 – 5y
8y + 26 = 2x
Question 2
2.
What type of lines are #1? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)

Question 3
3.
What is the solution?
2x – 6y + 9z = -8
5x + y + 2z = 10
3x + y – 8z = -28
Question 4
4.
What type of lines are #3? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)
Question 5
5.
What is the solution?
3x – 9y = 9
4x – 12y = 36
Question 6
6.
What type of lines are #5? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)
Question 7
7.
What is the solution?
4x + y – 3z = 45
6x – 4y + 3z = 41
2x – 7y – 11z = 85
Question 8
8.
What type of lines are #7? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)
Question 9
9.
What is the solution?
x – 5y + 3z = 39
3x + 8y – z = -19
2x – 6y – 5z = -29
Question 10
10.
What type of lines are #9? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)
