Grade 8

Practice

Match the lines and to the statements they represent:
Two lines in an x y plane. Line m passes through points E, B, and D. Point E is at 13 comma 3. Point B is at 6 comma negative 4. Point D is at 2 comma negative 8. Line n passes through points A, B, and C. Point A is at negative 2 comma 4. Point B is at 6 comma negative 4. Point C is at 12 comma negative 10.
1. A set of points where the coordinates of each point have a sum of 2
2. A set of points where the -coordinate of each point is 10 less than its -coordinate
Match the labeled points on the graph to statements about their coordinates:
1. Two numbers with a sum of 2
2. Two numbers where the -coordinate is 10 less than the -coordinate
3. Two numbers with a sum of 2 and where the -coordinate is 10 less than the -coordinate
