One way to answer this is by plugging each point for x and y in the equation as follows:
Then:
For (-26, 8), we have:
3 * (-26) - 8 * (8) = -142 (No).
For (-6, -4), we have:
3 * (-6) - 8 * (-4) = 14 (Yes).
For (10, 2), we have:
3 * (10) - 8 * (2) = 14 (Yes).
For (18, 5), we have:
3 * (18) - 8 * (5) = 14 (Yes).
For (22, -10), we have:
3 * (22) - 8 * (-10) = 146 (No).
Then, the points that lie on the graph of the line 3x - 8y = 14 are: (-6, -4), (10, 2), and (18, 5).
