Question

Describe and correct the error in solving the system of linear equations:

y= -2 x + 4y, y= -2 x + 6 the lines have the same slope so they are infinitely many solutions

Answer 1

different y-intercepts: no solutions

Explanation:

They would have infinitely many solutions if they had the same slope and the same y-intercept. However, they have the same slope and different y-intercepts, so they are parallel lines. There are no solutions.
