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) = (-7, 0) and (x2, y2) = (0, 9).
\n" ); document.write( " Slope a is .
\n" ); document.write( " Intercept is found from equation \"a%2Ax%5B1%5D%2Bb+=+y%5B1%5D\", or \"1.28571428571429%2A-7+%2Bb+=+9\". From that,
\n" ); document.write( " intercept b is \"b=y%5B1%5D-a%2Ax%5B1%5D\", or \"b=0-1.28571428571429%2A-7+=+9\".
\n" ); document.write( "
\n" ); document.write( " y=(1.28571428571429)x + (9)
