You can put this solution on YOUR website!
first use the two-point form:
\n" ); document.write( "(–9, –5) and (2, –4)
\n" ); document.write( "x1 y1 x2 y2 = –9 –5 2 –4
\n" ); document.write( "plug x1 y1 x2 y2 into: https://sooeet.com/math/linear-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "slope (m) = 0.0909090909 ~= 0.091 = 91/1000
\n" ); document.write( "y-intercept = -4.18181818 ~= -4.181
\n" ); document.write( "---
\n" ); document.write( "write the equation in point-slope form:
\n" ); document.write( "y + 5 = 0.091(x + 9)
\n" ); document.write( "---
\n" ); document.write( "rewrite the equation in standard form using integers:
\n" ); document.write( "y + 5 = (91/1000)(x + 9)
\n" ); document.write( "y + 5 = (91/1000)x + 819/1000
\n" ); document.write( "(91/1000)x + (-1)y = 5 - 819/1000
\n" ); document.write( "(91/1000)x + (-1)y = 5000/1000 - 819/1000
\n" ); document.write( "(91/1000)x + (-1)y = 4181/1000
