Question

Guided Practice

Write an equation for the line that is perpendicular to the given line and that passes through the given point.


4x – 2y = 9; (8, –2)


A.
y=−1/2x−9/2


B.
y=1/2x+2


C.
y=−1/2x+2

Answer 1

C.

y=−1/2x+2

Explanation:

Find the negative reciprocal of the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line perpendicular to 4 x − 2 y = 9 .

y = − 1 /2 x + 2
