Answer:7 Feet below ground
Step-by-step explanation:
1st: Since it says our hole is dug down 8ft to begin with we can start with x=-8
2nd: After a short break, it says we dug down another 3 feet which is -8-3=-11 which shows we are 11 feet below ground where the negative number showcases we are below ground level.
3rd:
After this we are shown a tractor accidentally fills in the hole with 4ft of dirt which signifies that we lose some of our holes height below ground so we would add four: -11+4=-7 this shows that we are finally seven feet below ground.
Answer:
y=3/2x-5/2
Step-by-step explanation:
1.find the slope
y2-y2/x2-x1
2-(-1)/3-1
2+1/3-1
3/2 slope (m)
2.y-y1=m(x-x1)
y-(-1)=3/2(x-1)
y+1=3/2x-3/2
y=3/2x-3/2-1
y=3/2x-5/2
