If point a is located at (-7,-3) and there are 12 points between a and b what could be the possible cordinates for point b

KonstantinChe [14]

Answer:

(-19,-3) or (5, -3)

Step-by-step explanation:

If b is located to the left side of a, then we need to add (-12) to the x-coordinate of a

b(-7+ [-12],-3) = b(-19,-3)

If b is located to the right side of a , then we need to add 12 to the x-coordinate of a.

b( -7+ 12, -3)= b(5 , -3)
