Thank you for your answer. To clarify on Step 3, why substitute X-coordinate with (2k) instead of (3k-6). Like wise for Y-coordinate?
The coordinate is always in this format (x,y) . Agree? Since it states the point is (2k, 3k-6) . So the x coordinate is 2k and y coordinate is 3k-6.
Sub the coordinates into the line of equation y = 3x + 15 .
Sub the coordinates into the line of equation y = 3x + 15 .
Thank you very much. Fully understand the logic.

Step 1 - substitute your coordinates into the equation, replacing x and y
Step 2 - is what you will get after substitution
Step 3 - Cross multiply to remove the denominator
Step 4 - solve for k

Thank you for your answer and explanations. May I clarify, why (y) substituted with (3k-6) and (x) substituted with (2k), can it be substituted vice versa.
