Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"7+x+%2B+-2+y+=+14\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-7%2F-2\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 14/7 = 2.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 14/-2 = -7.
  • Slope is -7/-2 = 3.5.
  • Equation in slope-intercept form: y=3.5*x+-7.
