One that could be close is Letter B?
Step-by-step explanation:
Start with a point on (0,6) This is because the 6 represents the point on the y - axis
Then, move up 1 and 3 to the right; This should result with a point on (3,7)
Keep repeating this to get your line
Total no. of students - 140 students
Total no. of students from all schools= 140+70+35+105=350
school A= 140÷350×100=40./. (multiplying by 100 because it's the total percentage )
School B = 70÷350×100=20./.
School C = 105÷350×100=30./.
School D = 105÷350×100= 10./.
Consisting all the schools percentage it gives 100./.
Hope this helps
