Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"3+x+%2B+-7+y+=+-6\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-3%2F-7\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -6/3 = -2.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -6/-7 = 0.857142857142857.
  • Slope is -3/-7 = 0.428571428571429.
  • Equation in slope-intercept form: y=0.428571428571429*x+0.857142857142857.
