(4 - -2) / (9 - 5) = 6/4 or 3/2
-t=9(t-10)
-t=9t-90
90=9t+t
90=10t
90/10=t
9=t
8. You can graph this or use the summation function on the TI computer.
The greatest common factor would be 1 because you need to factor both 14 and 55 so factor 14 and you get 2 and 7 factor 55 you get 5 and 11 the the GCF has to be 1
I hope this is helpful
