Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"4+x+%2B+2+y+=+12\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-4%2F2\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 12/4 = 3.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 12/2 = 6.
  • Slope is -4/2 = -2.
  • Equation in slope-intercept form: y=-2*x+6.
