Answer:
neon: 0 percent change oxide: -2 percent change copper: 2 percent change tin: 0 percent change
Step-by-step explanation:
Neon: -10+10=0
Oxide: -10+8=-2
Copper: -27+29=2
Tin: -50+50=0
Hope this helps
To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
