How do you write the equation of a line that passes through (2,3) and is perpendicular to y=2x+1

Question

nikato · Answer

do you know the relation between a line and its perepndicular?

anonymous · Answer

no i do not

anonymous · Answer

A perpendicular slope is the negative reciprocal of the slope of the original equation

anonymous · Answer

Do you know point slope form

nikato · Answer

well its simple.
say you have a line with a slope of 5. its perpendicular buddy would be the negative recipricol which is -1/5

anonymous · Answer

My teacher doesnt teach me well i just need instructions on how to do it and ill be golden

nikato · Answer

so what would be the slope of its perpendicular(your equation)

anonymous · Answer

im not sure honestly

anonymous · Answer

so the equation for point slope form is $$y - y _{1} = m(x - x _{1})$$m = slope

nikato · Answer

ok, so do you understand the equation y=mx + b.|dw:1383719025669:dw|
and thats the equation you were givien, or just in that format
