- 2. Multiple ChoiceIf a system of linear equations has one solution, what does this mean about the two lines?Parallel linesthe same lineIntersecting lines
- 3. Multiple ChoiceIf a pair of linear equations is consistent, then the lines will beparallelalways coincidentintersecting or coincidentalways intersecting
- 4. Multiple ChoiceFor what value of k, do the equations 3x – y + 8 = 0 and 6x – ky = –16 represent coincident lines?1/2−1/22−2
- 5. Multiple ChoiceThe equations 4x + 3y – 1 = 5 and 12x + 9y = 15 representNo solutionInfinite many solutionUnique solution
- 6. Multiple Choice
There are 50 donkeys and chickens on a farm. There are a total of 174 legs. Which system below can be used to figure out how many of each animal the farm has?
d + c = 174
4d + 2c = 50
d + c = 50
4d + 2c = 174
d + c = 50
2d + 4c = 174
d + c = 174
2d + 4c = 50
- 7. Multiple Choice
