Solved by pluggable solver: Find the equation of line going through points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (5, 2) and (x2, y2) = (7, -8).
\n" ); document.write( " Slope a is \"a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%28-8-2%29%2F%287-5%29+=+-5\".
\n" ); document.write( " Intercept is found from equation \"a%2Ax%5B1%5D%2Bb+=+y%5B1%5D\", or \"-5%2A5+%2Bb+=+27\". From that,
\n" ); document.write( " intercept b is \"b=y%5B1%5D-a%2Ax%5B1%5D\", or \"b=2--5%2A5+=+27\".
\n" ); document.write( "
\n" ); document.write( " y=(-5)x + (27)
\n" ); document.write( "
\n" ); document.write( " Your graph:

\n" ); document.write( "
\n" ); document.write( "

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, your line is \"y=-5x+%2B+27\"
