Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"-3+x+%2B+1+y+=+-4\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+--3%2F1\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -4/-3 = 1.33333333333333.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -4/1 = -4.
  • Slope is --3/1 = 3.
  • Equation in slope-intercept form: y=3*x+-4.
