Answer 1

Option B:

The equation of the given line is y = –4.

Solution:

The points on the line are (–3, –4) and (1, –4).

Here,
`x_1=-3,y_1=-4,x_2=1,y_2=-4`

Slope of the line:

`$m=(y_2-y_1)/(x_2-x_1)`

`$m=(-4-(-4))/(1-3)`

`$m=(-4+4)/(-2)`

m = 0

Slope of the line is 0.

Using point-slope formula,

`y-y_1=m(x-x_1)`

Here,
`x_1=1, y_1=-4, m=0`

`y-(-4)=0(x-1)`

y + 4 = 0

y = –4

The equation of the given line is y = –4.

Hence option B is the correct answer.
