Write an equation of a line that passes through the point (4,3)(4,3) and is perpendicular to the graph of the equation y=-1/3 x+4

Question

this is a question from my math homework and i need help

Answer 1

One (4,3) oughta do it. :-)

 

Anyway, you have a line with slope = -1/3. A line perpendicular to that has to have slope that's the negative reciprocal, or 3.

 

So we have a slope and a point. The line in point-slope form is

 

(y-3) = 3(x-4).

 

You can convert that to another form if you need to. Cheers!
