- Identify pair of real numbers as an ordered pair.
- Recognize an ordered pair through different examples.
- Describe rectangular or Cartesian plane consisting of two number
lines interesting at right angles at the point O.
- Identify origin (O) and coordinate axes (horizontal and vertical axes
or x-axis and y-axis) in the rectangular plane.
- Locate an ordered pair (a, b) as a point in the rectangular plane and
recognize. (i) a as the x-coordinate (or abscissa), (ii) b as the y-coordinate (or ordinate).
- Draw different geometrical shapes (e.g., line segment, triangle and
rectangle etc.) by joining a set of given points.
- Construct a table for pairs of values satisfying a linear equation in
two variables.
- Plot the pairs of points to obtain the graph of a given expression.
- Choose an appropriate scale to draw a graph.
- You can also download the 9th class math chapter 8 question answer pdf download for free.
- Draw a graph of, (i) An equation of form y = c, (ii) An equation of form x = a, (iii) An equation of form y = mx, (iv) An equation of form y = mx + c.
- Draw a graph from a given table of (discrete) values.
- Solve appropriate real life problems.
- Interpret conversion graph as a linear graph relating to two
quantities which are in direct proportion.
- Read a given graph to know one quantity corresponding to another.
- Read the graph for conversions of the form. (i) miles and kilometers, acres and hectares, (ii) degrees Celsius and degrees Fahrenheit, (iii) Pakistani currency and another currency, etc.
- Solve simultaneous linear equations in two variables using graphical
method.
- Cartesian Plane and Linear Graphs:
- An Ordered Pair of Real Numbers: An ordered pair of real numbers x and y is a pair (x, y) in which elements are written in specific order.
i.e., (i) (x, y) is an ordered pair in which first element is x and
second is y. such that (x, y) ≠ (y, x) where x ≠ y. (ii) (2, 3) and (3, 2) are two different ordered pairs.
(iii) (x, y) = (m, n) only if x = m and y = n.
Recognizing an Ordered Pair:
- In the class room the seats of a student is the example of an ordered pair. For example, the seat of the student A is at the 5th place
in the 3rd row, so it corresponds to the ordered pair (3, 5). Here 3
shows the number of the row and 5 shows its seat number in this
row.
- Similarly an ordered pair (4, 3) represents a seat located to a
student A in the examination hall is at the 4th row and 3rd column i.e.
3rd place in the 4th row.
