### 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.
