Answer:
Step-by-step explanation:
Y=mx+b
Slope (m) is rise over run.
1. rise= 4 run=5 therefore, slope=4/5
y=4/5x+b
b= y intercept
b= 4
Y=4/5x+4
2. rise= 1 run= 2 slope = -1/2
b= -1
Y= -1/2x - 1
Well, f 80% is 60 marks, you'll need 20% more to make it full, so it would be 15 more marks, which would be 75 total marks = 100% =)
I hope I helped! =D
