What are you trying to find X or Y ?
That's an increase of 14,000 people from the year 1995. The year 2000 would be 5 years later. We compare this increase of 14,000 to the original population, 20,000, and get:
14,000
------------- * 100% = 70%
20,000
The equation of the line passes through the point and has a slope is .

What are a line and the slope of a line?</h3>
Line:
- A line has only one dimension i.e., length and no width.
- It is formed with an infinite number of points lying on it.
- It can be extended infinitely along a straight path in both directions.
- An infinite number of lines pass through a given point, and a unique straight line can be drawn if any two points on that line are shown.
The slope of a line:
The slope of a line is the tangent value of the angle i.e., , where is the angle made by the line with the positive -axis.
Equation of a line:
The equation of a line in slope-intercept form is given by , where is the slope of the line and is the intercept of the line.
Here, we want to find the equation of the line which passes through the point and has a slope .
So, put in and obtain .
Now, since the line passes through the point , put and in to obtain:
Therefore, after substituting in , we obtain the required equation of the line that is .
So, the equation of the line that passes through the point and has a slope is .
Answer:
<h3>
present age of son = 10 </h3><h3>
present age of father = 40</h3>
Step-by-step explanation:
Let, present age of son be 'x'
present age of father be 'y'
y = 4x→ equation ( i )
After five years,
Son's age = x + 5
father's age = y + 5
According to Question,
Put the value of y from equation ( i )
Distribute 3 through the parentheses
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S. and change its sign
Collect like terms
Calculate the difference
Now, put the value of X in equation ( i ) in order to find the present age of father
plug the value of X
Calculate the product
Therefore,
Present age of son = 10
present age of father = 40
Hope this helps..
