Math Problem Statement
What is the image of left parenthesis, 5, comma, minus, 4, right parenthesis(5,−4) after a dilation by a scale factor of 44 centered at the origin?
Solution
To determine the image of the point after a dilation by a scale factor of centered at the origin, we apply the following rule:
where:
- is the original point,
- is the scale factor,
- is the new point after dilation.
Given:
- ,
- .
We calculate:
- ,
- .
Thus, the image of is:
