If point C (-2, 3) is translated up 3 units, then what are the coordinates of its image C’ ?
A (1, 3)
B (-2, 6)
C (-2, 0)
D (-5, 3)
x values do not change if x is horizontal
y values increase by 3 if y is positive up
(-2 , 3+3) = (-2 , 6)
To find the coordinates of the image C' after translating point C (-2, 3) up 3 units, we need to add 3 to the y-coordinate of C.
Therefore, the coordinates of the image C' are (-2, 6).
So, the correct answer is B) (-2, 6).
To find the coordinates of the image C' after translating point C (-2, 3) up 3 units, you need to add 3 to the y-coordinate of point C.
Step 1: Take the coordinates of point C (-2, 3).
Step 2: Add 3 to the y-coordinate, as the point needs to be translated up 3 units.
Step 3: The x-coordinate remains the same as there is no horizontal translation.
So the coordinates of the image C' would be (-2, 3+3), which simplifies to (-2, 6).
Therefore, the correct answer is B: (-2, 6).
