Question

-

A line is perpendicular to y = {x-9
and intersects the point (3,2).
What is the equation of this
perpendicular line?
y = -2x + [?]
Hint: Use the Point-Slope Form: y - y1 = m(x– x1)
Then write the equation in slope-intercept form.

Answer 1

y=-2x+8.

Explanation:

Perpendicular to y=1/2x-9

Get slope by getting negative reciprocal

1/2 into -2

2 = 3(-2) + b

2 = -6 + b

8 = b

y=-2x+8
