The nearest distance between the points (8,1) and (2,10) is 11 units, which is mentioned in and also calculated by using formula.
Step-by-step explanation:
The given is,
Two points are (8,1) (2,10)
Step: 1
By graphical method, refer the attachment,
First point (8,1)
The values of x=8 and y=1 noted in the graph
Second point (2,10)
The values of x=2 and y=10 noted in the graph
Now join the two points (8,1) and (2,10)
Measure the distance between two points, the distance is 11 units. Due to some error the value becomes 10.98 or 11.1 we need to convert the answer into nearest whole number.
( OR )
Step:1
By formula method,
Distance = .....................(1)
Where,
(8,1) are ()
(2,10) are ()
From the equation,
=
=
=
=
= 10.81665
≅ 11 ( Answer convert to the nearest tenth)
Distance = 11 units
Result:
The nearest distance between the points (8,1) and (2,10) is 11 units, which is mentioned in and also calculated by using formula.
Answer:
Option C is correct option.
Step-by-step explanation:
We need to find k constant of proportionality
In the graph below let us take the values of x and y
x=150 , y=50
x=300, y=100
x=450, y=150
Now finding k using the formula:
Putting values of x and y to find k
For x=150 , y=50 k = 50/150, k =1/3
For x=300, y=100 , k=100/300 , k=1/3
For x=450, y=150, k= 150/450 , k=1/3
Since for values of x and y, k = 1/3 is constant so, the graph shows two quantities that vary directly.
So, Option C is correct option.
