\n" ); document.write( "given:
\n" ); document.write( "f(x) = (-1/7)x + 8
\n" ); document.write( "(5,9)
\n" ); document.write( "---
\n" ); document.write( "perpendicular lines have negative reciprocal slopes.
\n" ); document.write( "---
\n" ); document.write( "therefore, the slope of the perpendicular line = 7
\n" ); document.write( "---
\n" ); document.write( "to solve the linear equation, copy and paste this (the given point and the perpendicular slope):
\n" ); document.write( "5,9,7
\n" ); document.write( "into the \"Point-Slope form: x1 y1 m\" input box here: https://sooeet.com/math/linear-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "y-intercept = -26
\n" ); document.write( "slope = 7
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "slope-intercept form:
\n" ); document.write( "y = 7x - 26
