Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"-2+x+%2B+1+y+=+3\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+--2%2F1\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 3/-2 = -1.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 3/1 = 3.
  • Slope is --2/1 = 2.
  • Equation in slope-intercept form: y=2*x+3.
