Answer:
1.125 or 9/8
Step-by-step explanation:
5/8 is .625 and 3/6 is .5 so .625+.5=1.125
The number is 17 61/100. 61/100 can't be reduced, because 61 is a prime number.
Rearrange the formula given to determine the slope, you will see that in y=mx+b form the slope is -2/3
You now have the slope (m) and two test points. Input those values into y=mx+b and you will have your answer!
I got y=(-2/3)x+(22/3) which I'm quite certain is correct.
