Compare the line passing through the points (−3, −11) and (6, 4) to the line given by the equation y=35x−6.

Question

A.	They have the same slope.
	B.	They have the same x-intercept.
	C.	The two lines are perpendicular.
	D.	They have the same y-intercept.

I say c if it is wrong what is right answer?

Steve · Answer

slope = 15/9 = 5/3
y-4 = 5/3 (x-6)
y = 5/3 x - 6

The lines are not perpendicular, because the slopes are not negative reciprocals.

The line through the points is perpendicular to

y = -3/5 x - 6

However, they do both have a y-intercept of -6.

Sir · Answer

Sir 2.0 you typed the QUESTION WRONG!! NOW I HAVE TO WASTE TIME TYPING THIS RESPONSE!!! that being said the equation SHOULD be y=3/5x-6 and the answer is C. The two lines are perpendicular.
