Which system of equations has infinitely many solutions?

3y = –5x + 7

3x = –5y – 7

3y = x – 4

3x – 9y = –12

2x + y = 2

–4x – 2y = 4

2y = 3x + 6

4y = 6x + 12

Which system of equations has no solution?

3y = 1 + x

y = –2x + 5

4x – 5y = 3

–3 = 4x – 5y

5x + 4y = 1

4x – 2y = 4

y = –3x + 4

y = (–3/4)x + 1

Suri makes $15 per hour and gets a weekly bonus of $25. Juan makes $14 per hour and gets a weekly bonus of $50. Is it possible for Suri and Juan to make the same amount of wages, y, by working the same number of hours, x, in one week?

Yes because the slopes of the equations are different so the system of equations will have one solution.

No because the slopes of the equations are the same so the system of equations will have no solution.

Yes because the slopes of the equations are the same so the system of equations will have no solution.

No because the slopes of the equations are different so the system of equations will have one solution.
