Question

Find the equation of the line through (-1, 3) and (5,3)

Answer 1

Given:

A line passes through (-1, 3) and (5,3).

To find:

The equation of the line.

Solution:

The line passes through (-1, 3) and (5,3). So, the equation of the line is

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`

`y-3=(3-3)/(5-(-1))(x-(-1))`

`y-3=(0)/(5+1)(x+1)`

`y-3=0`

Adding 3 on both sides, we get

`y-3+3=0+3`

`y=3`

Therefore, the equation of the line is
`y=3`.
