This graph shows the per cent of students who dropped out of school after completing High School. The point labelled A shows that, in 1996, about 4.7% of students dropped out.

  1. In which year was the dropout the rate highest? In which year was it the lowest?
  2. When did the per cent of students who dropped out of high school first fall below 5%?
  3. About what per cent of students dropped out of high school in 2007? About what per cent of students stayed in high school in 2008?

उत्तर

Observing the graph carefully, we have

  1. The drop out rate was the highest in the year 1990 and the least in 2000.
  2. In the year 1996, the per cent of students dropped out of high school first fall below 5%.
  3. About 4.7% students dropped out of high school in 2007.

(1, 3), (2, 3), (3, 3), (4, 3)


In the given graph the coordinates of point x are ______.


The process of fixing a point with the help of the coordinates is known as ______ of the point.


A point has 5 as its x–coordinate and 4 as its y–coordinate. Then the coordinates of the point are given by ______.


The distance of any point from the x-axis is called the x-coordinate.


Match the ordinates of the points given in Column A with the items mentioned in Column B.

Column A Column B
(a) (7, 0) (i) The ordinate is double the abscissa.
(b) (11, 11) (ii) The ordinate is zero.
(c) (4, 8) (iii) The ordinate is equal to the abscissa.
(d) (6, 2) (iv) The abscissa is double the ordinate.
(e) (0, 9) (v) The abscissa is triple the ordinate.
(f) (6, 3) (vi) The abscissa is zero.

If y-coordinate is 3 times x-coordinate, form a table for it and draw a graph.


Draw a parallelogram ABCD on a graph paper with the coordinates given in Table I. Use this table to complete Tables II and III to get the coordinates of E, F, G, H and J, K, L, M.

Point (x, y)
A (1, 1)
B (4. 4)
C (8, 4)
D (5, 1)

     Table I

Point (0.5x, 0.5y)
E (0.5, 0.5)
F  
G  
H  

     Table II

Point (2x, 1.5y)
J (2, 1.5)
K  
L  
M  

    Table III

Draw parallelograms EFGH and JKLM on the same graph paper.

Plot the points (2, 4) and (4, 2) on a graph paper, then draw a line segment joining these two points.


Extend the line segment on both sides to meet the coordinate axes. What are the coordinates of the points where this line meets the x-axis and the y-axis?


Consider this input/output table.

Input 1 2 4 5 7
Output 2 5 11 14 20
  1. Graph the values from the table by taking Input along horizontal axis from 0 to 8 and Output along vertical axis from 0 to 24.
  2. Use your graph to predict the outputs for inputs of 3 and 8.
