Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"-5+x+%2B+8+y+=+-40\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+--5%2F8\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -40/-5 = 8.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -40/8 = -5.
  • Slope is --5/8 = 0.625.
  • Equation in slope-intercept form: y=0.625*x+-5.
