Draw the graph of each of the equations given below. Also, find the co-ordinates of the point where the graph cuts the co-ordinates axis:

(a) 6x - 4y = 12

(b) 4y -x= 8

To draw the graph, we need at least two solutions of the equation We can get two points by putting x=0 and y=0. And then draw the graph. Corrdinates will be given by (x,0) and (0,y)

a.

Coordinates are (2,0) and (0,-4)

b.

Coordinates are (-8,0) and (0,2)

The taxi fare in a delhi is as follows: For the first kilometer, the fare is Rs16 and for the subsequent distance it is Rs 10/km. Taking the distance covered as x km and total fare as Rs y, write a linear equation for this information, and draw its graph.

Total fare = Fare of first kilometer + 10 × subsequent distance travelled

$y= 16 + 10 (x-1)$

$y=16 + 10x- 10$

$y=6+10x$

We can draw the graph by putting points x=0 and x=1

If a linear equation has solutions (-2, 2), (0, 0) and (2, -2), then it is of the form

(a) y - x = 0

(b) x + y = 0

(c) -2x + y = 0

(d) -x + 2y = 0

Answer (b)

Which of the below statement is true

(a) A linear equation x + 3y = 5 has a unique solution

(b) The graph of the equation y = x + 1 passes through the origin

(c) The line parallel to the y-axis at a distance 4 units to the left of y-axis is given by the equation y = - 4

(d) None of the above

Answer (d)

Any point on the y-axis is of the form

(a) (x, 0)

(b) (x, y)

(c) (0, y)

(d) ( y, y)

Answer (C)

Draw the graph of the equation 2x + 3y = 12. From the graph, find the coordinates of the point:

Whose y- coordinate is 3

Whose x- coordinate is -3.

Draw the graph of the equation 2x + y = 6. Shade the region bounded by the graph and the co- ordinate axis. Also find the area of shaded region.

The graph of the equation 2x + y = 6 can be drawn by choosing points x=0 i.e y=6 and y=0 i.e x=3

Shading the region bounded by the graph and the co- ordinate axis

This is a right angle triangle with base =3 and height =6

So area = $\frac {1}{2} \times 6 \times 3 = 9 $units

Draw the graph of the equation $ \frac {x}{2} + \frac {y}{3} =1$. Also find the area of triangle formed by the line and the co-ordinates axis.

The graph of the Linear equation $ \frac {x}{2} + \frac {y}{3} =1$ can be drawn by choosing points x=0 i.e y=3 and y=0 i.e x=2

Now the triangle formed by the line and co-ordinates axis is given as below

This is a right angle with base as 2 units and height ad 3 units.

So ,Area = $\frac {1}{2} \times 2 \times 3= 3$ units

Draw the graph of y = x + 2

We can get two points by putting x=0 and y=0. And then draw the graph. Corrdinates will be given by (x,0) and (0,y)

Draw the graphs of the linear equations 4x - 3y + 4 = 0 and 4x + 3y - 20 = 0. Find the area bounded by these lines and x = axis.

The graph of 4x - 3y + 4 = 0 by putting y=0 i.e x= -1 and x=2 i.e y =4

Similarly the graph 4x + 3y - 20 = 0 by putting y=0 i.e x=5 and x=2 i.e y=4

Now we can see that area bounded by these lines and x = axis is a triangle with base = 6 unit and height =4 units.

So area = $\frac {1}{2} \times 6 \times 4 = 12 $units

Solve for y:

(3y+2)/7+ (4 (y+1))/5= 2/3 (2y+1)

The angles of a triangle are 5x, 3 (2x - 5) and 9x -5 Find x and also name the triangle.

We know that sum of the angles in the triangle is equal to 180

Therefore,

$5x + 3(2x - 5) + 9x -5=180$

$20 x -20 =180$

$x= 10$

Therefore angles are

50°, 45° , 85°

The name of the triangle is scalene triangle

Determine the point on graph of equation 2x + 5y = 20 whose x - co-ordinate is 5/2 times its ordinate.

If (2a,a-1) is a solution of 2x + 3y - 9 = 0, find a

If (2a,a - 1) is the solution ,then putting x=2a and y=a-1

$2(2a) + 3(a-1) -9=0$

$4a + 3a -3 -9=0$

$a= 12/7$

Draw the graph of linear equation x = 3y

We can draw the graph by joining for points (0,0) and (3,1)

Draw the graph of linear equation 2x -9 = 0

This can be treated as equation in two variable as $ 2x + 0 \times y -9=0$

Drawing the graph by putting y=0 and y=2

Draw the graph of linear equation x = y

We can draw the graph by joining for points (0,0) and (1,1)

Draw the graphs of linear equation y = x and y = -x on the same Cartesian plane, what do you observe?

Here is the graph

We can observe that both the graph are symmetrical on both the x-axis and y-axis

Find three different solutions of the equation 4x + 3y = 12 from its graph?
