A line has a slope of –5 and a y-intercept of (0, 3). What is the equation of the line that is perpendicular to the first line and passes through the point (3, 2)?

Question

nincompoop · Answer

what does it mean when a line is perpendicular to another line?

anonymous · Answer

Find the slope of the perpendicular line by doing m_1 * m_2 =-1

anonymous · Answer

Perpendicular equations are the opposite signs of the given points. at least that's how I learned how to do it.

anonymous · Answer

y=mx+b

nincompoop · Answer

a line is perpendicular to another line IF its slope is a negative reciprocal of the other line 

example:
if the first line has a slope of 5 
then the line perpendicular to it has a slope of - 1/5 

if the first line has a slope of -2/5 
then the line perpendicular to it is 5/2 

do you need further clarification?

@Gio333 if you are not going to respond, you might as well log off and go to sleep

sorry i was trying to figure it out

dan815 · Answer

y- 2=1/5(x-3,)

gio333 · Answer

is the answer y=-2x+7?

dan815 · Answer

if m1=a/b
and m2 is perpendiculap slope then = -b/a

dan815 · Answer

a line that passes through a point (a,b) and has slope m=
y-b=m(x-a)

dan815 · Answer

you can re arrange this equation for a slope intercept form
y=mx-ma+b
