Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"3+x+%2B+-4+y+=+8\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-3%2F-4\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 8/3 = 2.66666666666667.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 8/-4 = -2.
  • Slope is -3/-4 = 0.75.
  • Equation in slope-intercept form: y=0.75*x+-2.
