Move the x over to the other side
2y=10-5x
Divide both sides by 2 to get the y alone
y=-5/2x+5
Find m from the equation of a line (y=mx+b)
m=-5/2
Slope=-5/2
The probability of obtaining a 1 is 1/13, so the probability of not getting a 1, that is, the probability of getting a ball different from 1, is 1- (1/13)=12/13, which is 0.923
I believe the answer is 5 • (f - 32)<span> / 9 </span>
