The answer is:
B. -1/2
Explanation:
The equation is in y= mx + b form, which means that m= slope and b= y-intercept. You can see that the slope is -1/2.
Hours spent on project= p
4p+2=16 hours
4p=14
p=3 and a half hours
6.8
= 6 + 0.8
= 6 + 8/10 (simplifying...)
= 6 + (8 : 2)/(10 : 2)
= 6 + 4/5
= 6 4/5 <----- this is the answer.
I hope this helps. =)
