Answer:
y=-1/2x+2
Step-by-step explanation:
slope is -1/2 beware this is a negitive slope so it goes down like this \
go one up and go to the left 2 times and connect the dots
The GCF of 8x and 40 is 8
40 | 2
20 | 2
10 | 2
5 | 5

8 | 2
4 | 2
2 | 2

40 = 2³ * 5
8 = 2³
We take only common factors with lowest exponent.
So 2³ = 8
