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:

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-4-(-4)}{1-3}$

$m=\frac{-4+4}{-2}$

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.
