Study Notes

Equations and Solutions

y = 2x + 5 results in the point (2, 9)
y = -2x + 4 yields the point (3, -2)
y = 3x - 7 reaches the point (1, -4)
y = 4x - 9 leads to the point (3, 3)

Additional Equations

y + 2 = -3(x - 4) gives the point (4, -2)
y - 3 = 2(x + 1) produces the point (-1, 3)
y - 4 = -2(x + 3) results in the point (-3, 4)

Linear Combinations

2x + 3y = 5x - y corresponds to the point (0, 0)
2x + 3y = 12 results in the point (-6, 8)
-3x + 7y = 5x + 2y leads to the point (-5, -8)

More Linear Equations

4x + y = 10 gives the point (4, -6)
-4x - y = 24 results in the point (-8, 8)
5x - 2y = 30 produces the point (8, 5)
6x + 7y = 4x + 4y corresponds to the point (6, -4)
x - 5y = -15 results in the point (-5, 2)
