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
if you look at delta y over x, you'll notice it always equals 2
i.e (22-2)/10-0 = 20/10 = 2
or (14-2)/6-0 = 12/6 = 2
or even (22-8)/10-3 = 14/7 = 2
This means that m (slope) is 2.
Now as for b. b is the y intercept and that value occurs when x = 0. On the table, when x = 0 y = 2 so b = 2.
y = mx + b becomes
y = 2x + 2
Y-intercept: Let x = 0. Result: 5x=0, and x= 0. y-intercept is (0,0).
Similarly, x-int. is (0,0) (after going thru the same procedure: set y=0 and find x)
Answer:
x intercept (3,0)
y intercept (0,-3)
Step-by-step explanation:
4(a-2)=3(a+4)
4a-8=3a+12
a=20
