If y varies directly as x and y= 24 when x= 40, find y when x= -35

Question

I have home I just don’t really understand cause I was absent the day they taught this so can you pls tell me the answer

Answer 1

You can work this as a proportion.

 

y/x = constant

 

24/40 = y/-35

 

y = -35(24/40) = -21
