1st one is 0
2nd one is -3
3rd one is -2
4th one is 5
Combine like terms, isolate the variable, and make the slope of the variable 1 to find all the answers.
Answer: 1.5
Step-by-step explanation: In order to find the scale factor, all you would need to do is pick 2 sides that are the similar (in this case, 6 and 9), and divide them.
9/6 = 1.5
And that will give you the scale factor!
