All you need to do is subtract.
1-5 is -4. 1-3 is -2 thus (-4,-2)
4-5=-1. 2-3=-1 thus (-1,-1) at this point there is only one option left
B Is the answer
Answer:x=7 y=5
Step-by-step explanation:
I just took it, sorry I'm not good at math and just guessed until I got it right for this answer.
Answer:
Yes, they are proportional.
Step-by-step explanation:
Using this from what I found helped me answer the question, and if you compare their ratios, they are both going to show that 75% each class have texted:
Proportional: When quantities have the same relative size. In other words they have the same ratio.
All you would have to do is compare the amount of students that texted(x) to the amount of students there are total in the class(y). When you compare them in a y:x format, it will all lead up to the results showing that 75% of both groups have texted.
Use the slope formula which is y2-y1/x2-x1. -1-4/5-(-2)= -5/7
