Answer:

The equation of line p is  y= 1/4x +6.  If line k contains the point (3,5) and is perpendicular to line p, find the equation of line k.

 

 

Possible Answers:

y = -4x + 17

y = 3x + 5

y = 4x - 17

y = 1/4x + 17

Correct answer:

y = -4x + 17

Explanation:

Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.  

hope it help;)
