Answer:
C: (12,4)
Explanation:
We can find the slope of the line with "rise over run"
The pattern is 1 unit up, 3 units to the right
By following this pattern from point (9,3),
we go 1 unit up on the y axis, moving (9,3) to (9,4)
Next we move 3 units right on the x-axis,
moving (9,4) to (12,4)
Answer is (12,4)
