Question

1. translating a shape 5 units left and 3 units up changes the coordinates of (4,9) to what?

a. (9,12)
b. (-1,12)
c. (7,4)
d. (-1,6)

Explanation:

Step1: Calculate new x - coordinate

Moving 5 units left means subtracting 5 from the x - coordinate. The original x - coordinate is 4, so the new x - coordinate is $4 - 5=-1$.

Step2: Calculate new y - coordinate

Moving 3 units up means adding 3 to the y - coordinate. The original y - coordinate is 9, so the new y - coordinate is $9 + 3 = 12$.

Answer:

B. $(-1,12)$
