Could someone please show me how to find the equation of a line that passes through (6,10) (8,7) I am really struggling with how to set this up and solve. Any help would greatly be appreciated.

\n" ); document.write( "The equation form is y = mx + b
\n" ); document.write( "You need to find \"m\" and \"b\".
\n" ); document.write( "--------------
\n" ); document.write( "m = slope = [10-7]/[6-8] = -3/2
\n" ); document.write( "-------------------------
\n" ); document.write( "Substitute m, x, and y into y=mx+b to find \"b\":
\n" ); document.write( "10 = (-3/2)(6)+b
\n" ); document.write( "10 = -9 + b
\n" ); document.write( "b = 19
\n" ); document.write( "--------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "y = (-3/2)x + 19
