Question

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

On a coordinate plane, a line goes through (negative 4, negative 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 (, 3)?

Answer:

y +3 = 1/2(x +4)

Explanation:

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (1 -(-3))/(4 -(-4)) = 4/8 = 1/2

The point-slope form of the equation for a line is ...

y -y1 = m(x -x1)

Filling in the known values, this is ...

y -(-3) = 1/2(x -(-4))

y +3 = 1/2(x +4)
