Question

The wind was blowing quite strongly when Jenny was baby-sitting. She was outside with the children, and they were throwing their large plastic ball up into the air. The wind blew the ball so that it landed approximately 3 feet east and 4 feet north of where it was thrown into the air.

Answer 2

Option d

Explanation:

If the ball landed 3 feet east of where it was thrown, then it moved 3 units horizontally along the x-axis.

If you moved 4 units to the north then we can say that 4 units were moved on the y axis

Therefore, the original matrix
`\left[\begin{array}{cc}x\\y\end{array}\right]` is transformed in the matrix
`\left[\begin{array}{cc}x+3\\y+4\end{array}\right]`

Therefore, the answer is
`\left[\begin{array}{cc}x+3\\y+4\end{array}\right]`
