The given line passes through the points (−4, −3) and (4, 1).



What is the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (−4, 3)?

y − 3 =
(x + 4)

Respuesta :

Answer:

y - 3 = -2(x + 4)

Step-by-step explanation:

First, we must find the slope of the line by using the two points.

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m = \frac{1-(-3)}{4-(-4)} = \frac{1+3}{4+4} = \frac{1}{2}[/tex]

The slope of a line that is perpendicular to another is the negative reciprocal of the other line's slope. So the slope of the line perpendicular to the given line is -2. Now we must write the equation in point-slope form:

[tex]y - y_{1} = m(x - x_{1})[/tex]

[tex]y - 3 = -2(x-(-4))[/tex]

[tex]y - 3 = -2(x + 4)[/tex]

Y=3= -2 (x + 4)

There u go!
