Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"0.75+x+%2B+-1+y+=+-2\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-0.75%2F-1\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -2/0.75 = -2.66666666666667.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -2/-1 = 2.
  • Slope is -0.75/-1 = 0.75.
  • Equation in slope-intercept form: y=0.75*x+2.
