Simultaneous Linear Equations Exercise Ex. 8.2

Solution 1(a)

The graph of x = 3 is as follows:

 

Solution 1(b)

Given equation, y + 5 = 0

i.e. y = -5

 

The graph is as follows:

 

  

Solution 1(c)

 

Solution 1(d)

 

Solution 2(a)

 

Thus, the graph of the equation meets the X-axis at (2, 0) and Y-axis at (0, 3).

Solution 2(b)

 

 

Thus, the graph of the equation meets the X-axis at (-6, 0) and Y-axis at (0, 45).

Solution 3

 

 

 

Solution 4

 

 

From the graph, we find that

 

a. When y = 1, x = 1.

b. When x = -2, y = -14

Solution 5

The graph is as follows:

 

 

From the graph, we find that p = -1 and q = -2.

 

Solution 6

The graph is as follows:

 

 

From the graph, we find that a = -1 and b = -9.
