3. A) y-intercept =5
Slope=(-4,10)
B) y=-4/10x+5
4. A) y-intercept=-1
Slope=(5,5)
B) y=5/5x-1
If you want to estimate to the tens, the answer is 680
If you want to estimate to the hundreds, the answer is 700
If you want to estimate to the thousands then the answer would be not an answer
The real answer without estimating is 681
28 feet
32 feet divided by 8 equals 4
so the lake is in sections of 4
take 4 times it by 7
answer is 28 feet
to check your answer 28/32 simplified is 7/8
