Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"4+x+%2B+5+y+=+10\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-4%2F5\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 10/4 = 2.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 10/5 = 2.
  • Slope is -4/5 = -0.8.
  • Equation in slope-intercept form: y=-0.8*x+2.
