So,

Answer is:

2.

(a)

So,

Answer is:

(b)

So,

Answer is:

(c)

So,

Answer is:

3.

Equation of line joining (1,7) and (-3,8) is given by:

i.e.

- 4 (y - 7) = x - 1

i.e.,

x + 4y = 1 + 28

So,

Answer is:

x + 4y = 29

4.

Equation of the given line is written as:

So,

Slope of the given line is:

So,

Slope of the required line is:

The required line passes through (2,4).

So,

Equation of the required line is:

y - 4 = 4 (x - 2)

i.e.,

y - 4 = 4x - 8

i.e.,

4x - y = 4

So,

Answer is:

4x - y = 4
