What's are you trying to find?
First, you have to divide 270 by 3, so you get 25%. This comes out to be 90. So, 90 is 25%. Now, multiply this by four to get 100%. This comes out to be 360. So, 270 is 75% of 360, which answers the question '270 is 75% of what number?'
1. y= -x + 3
2. y = x - 3
3. y = 3x + 1
4. y = -3x - 3
The other two vertices are (-3,6) and (-6,3)
