Question

Ryan, Jessica, and Mark each solved this system of equations. All of their answers are different. Find and explain the mistakes. What is the correct answer? y = 3x + 2 6x – 2y = 10

Answer 1

6x - 2y = 10

-2y = -6x + 10...reduce by dividing by -2

y = 3x - 5....slope = 3 and y int = -5

y = 3x + 2 ...slope = 3, y int = 2

These lines are parallel. Parallel lines will have the same slope, but different y int's. There is no solution to this because ur lines never intersect.

Mark's answer is correct

Answer 2

It's not possible to do any of that without seeing any of their work.

By the way, that system of equations has no solution.
