The numbers before the X are the slope, the numbers after the x are the Y- intercepts.
1. Slope = -3
2. y-intercept = -8
3. Slope = 5/4, y-intercept = 9
4. 8x+6y =12
subtract 8x from each side to get Y on the left side:
6y = -8x +12
Divide each term by 6:
y = -8x /6 + 12/6
y = -4/3x + 2
The answer is A.
5. Rewrite the equation in slope intercept form:
x-3y = -3
-3y = -x -3
y = 1/3x +1
The slope is 1/3, the y-intercept is 1
The correct line is B. line b

Answer:
Speed of boat in still water is 6km/h
Speed of current is 4km/h
Step-by-step explanation:
We know speed = distance / time
Let the speed of boat in still water be x
Let the speed of current be y
Hence the speed of boat, down stream =
Distance downstream = 20km
Time taken = 2 hours
We have
......(1)
Speed of boat upstream =
Distance upstream = 4
Time taken = 2
We have
...(2)
Adding (1) & (2)
Substituting in (1) we get
Assuming population increase has been linear here is the given data from the problem.
13090 - 12390 = 700 people
2010 - 2000 = 10 years
700 / 10 = 70 people per year
Based on the data, here is our equation
y = 70x + 13,090
b) 21,000 = 70x + 13,090
x = 113 years
113 + 2010 = Answer = year 2123
c) 0 = 70x + 13,090
x = -187
-187 + 2010 = Answer = year 1823
