To determine which equations are correct for each graph, we can use the given coordinate points (7,3) for Graph A and (7,0) for Graph B.
For Graph A (7,3):
To find the correct equation, we need to substitute the x and y values from the coordinate point into each equation option and see which equation holds true.
Let's go through each option:
1. y = 3/7x -> Substituting x = 7: y = (3/7)(7) = 3, which matches the y value (3). So, option 1 is correct.
2. y = 7/3x -> Substituting x = 7: y = (7/3)(7) = 49/3, which does not match the y value (3). So, option 2 is incorrect.
3. y = -7/3x -> Substituting x = 7: y = (-7/3)(7) = -49/3, which does not match the y value (3). So, option 3 is incorrect.
4. y = 3x -> Substituting x = 7: y = 3(7) = 21, which does not match the y value (3). So, option 4 is incorrect.
5. y = -3x -> Substituting x = 7: y = -3(7) = -21, which does not match the y value (3). So, option 5 is incorrect.
6. y = 7x -> Substituting x = 7: y = 7(7) = 49, which does not match the y value (3). So, option 6 is incorrect.
7. y = -7x -> Substituting x = 7: y = -7(7) = -49, which does not match the y value (3). So, option 7 is incorrect.
8. y = 3x + 7 -> Substituting x = 7: y = 3(7) + 7 = 21 + 7 = 28, which does not match the y value (3). So, option 8 is incorrect.
9. y = -3x + 7 -> Substituting x = 7: y = -3(7) + 7 = -21 + 7 = -14, which does not match the y value (3). So, option 9 is incorrect.
10. y = 7x + 3 -> Substituting x = 7: y = 7(7) + 3 = 49 + 3 = 52, which does not match the y value (3). So, option 10 is incorrect.
11. -7x + 3 -> Substituting x = 7: -7(7) + 3 = -49 + 3 = -46, which does not match the y value (3). So, option 11 is incorrect.
12. y = -3/7x -> Substituting x = 7: y = (-3/7)(7) = -3, which matches the y value (3). So, option 12 is correct.
Therefore, the correct equations for Graph A are:
1. y = 3/7x
12. y = -3/7x
Now let's move on to Graph B (7,0):
By using the same process as before, we can substitute the given x and y values into each equation option to determine which ones hold true for Graph B.
1. y = 3/7x -> Substituting x = 7: y = (3/7)(7) = 3, which does not match the y value (0). So, option 1 is incorrect.
2. y = 7/3x -> Substituting x = 7: y = (7/3)(7) = 49/3, which does not match the y value (0). So, option 2 is incorrect.
3. y = -7/3x -> Substituting x = 7: y = (-7/3)(7) = -49/3, which does not match the y value (0). So, option 3 is incorrect.
4. y = 3x -> Substituting x = 7: y = 3(7) = 21, which does not match the y value (0). So, option 4 is incorrect.
5. y = -3x -> Substituting x = 7: y = -3(7) = -21, which does not match the y value (0). So, option 5 is incorrect.
6. y = 7x -> Substituting x = 7: y = 7(7) = 49, which does not match the y value (0). So, option 6 is incorrect.
7. y = -7x -> Substituting x = 7: y = -7(7) = -49, which does not match the y value (0). So, option 7 is incorrect.
8. y = 3x + 7 -> Substituting x = 7: y = 3(7) + 7 = 21 + 7 = 28, which does not match the y value (0). So, option 8 is incorrect.
9. y = -3x + 7 -> Substituting x = 7: y = -3(7) + 7 = -21 + 7 = -14, which does not match the y value (0). So, option 9 is incorrect.
10. y = 7x + 3 -> Substituting x = 7: y = 7(7) + 3 = 49 + 3 = 52, which does not match the y value (0). So, option 10 is incorrect.
11. -7x + 3 -> Substituting x = 7: -7(7) + 3 = -49 + 3 = -46, which does not match the y value (0). So, option 11 is incorrect.
12. y = -3/7x -> Substituting x = 7: y = (-3/7)(7) = -3, which does not match the y value (0). So, option 12 is incorrect.
Therefore, there are no correct equations for Graph B based on the given coordinate point (7,0).
