given:
y = 7x - 4
(-2,3)
---
perpendicular lines have negative reciprocal slopes
so the perpendicular slope = -1/7 =
---
to solve the linear equation, copy and paste this (given point and perp slope):
-2,3,-0.1428571
into the "Point-Slope form: x1 y1 m" input box here: https://sooeet.com/math/linear-equation-solver.php
---
a = 0.1428571
b = 1
c = 2.7142858
---
answer:
the standard form equation is:
(0.1428571)x + y = 2.7142858
