The endpoints of sa020-1.jpg are A(9, 4) and B(5, β 4). The endpoints of its image after a dilation are sa020-2.jpg and sa020-3.jpg. Find the scale factor.
Accepted Solution
A:
Answer: The scale factor is (β10) / (4)
Explanation: The complete question as well as the rule for the distance between two points are shown in the attached image.
To get the scale factor, we will follow these steps: 1- Length of AB: AB =Β β(5-9)Β²+(-4-4)Β²Β AB =Β β80 AB = 4β5 units
