Question

Is anyone good at perpendicular equations?

Answer 1

it's easier when you post the specifics, if anyone knows, they'd help

Answer 2

what is the problem ?

Answer 3

Write the equation of the line passing through the point (4, -2) and perpendicular to y = \frac{ 1 }{3 }x - 7

Answer 4

\[y = \frac{ 1 }{3 }x - 7\]

Answer 5

here is the equation for finding the slope of a perpendicular line:

\[m_a * m_b = -1\]
where m_a is the slope of the first line, and
m_b is the slope of the perpendicular line

so you have m=1/3
let m be m_a
and plug it into the equation and solve for m_b, which is the slope of a perpendicular line:
\[(1/3) * m_b = -1\]

Answer 6

@DemolisionWolf Would it be -1, or -3? I thought the first step was to flip the fraction (irtwas 1/3, now 3/1) Then make it be - if it was + or + if it was -? :)
