Homework Statement
Find the slope of the line through x(2, -3) and y(1, 2).
What is the slope of any line perpendicular to xy?
Hence, find the equation of the line through the origin and which is perpendicular to xy.
Homework Equations
slope formula:
m = y2 - y1/ x2 - x1
equaltion of the line:
y - y1 = m(x - x1)
The Attempt at a Solution
m = y2 - y1/ x2 - x1
m = 2 + 3/ 1 - 2
m = 5/-1
m = -5
slope of any line perpendicular = 1/5
Eq. of line:
y - y1 = m(x - x1)
y + 3 = 1/5(x - 2)
5y + 15 = x - 2
x - 5y - 2 - 15 = 0
x - 5y - 17 = 0
i know that's wrong, just need a push in the right direction
