Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation -1+x+%2B+1+y+=+-4 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+--1%2F1.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -4/-1 = 4.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -4/1 = -4.
  • Slope is --1/1 = 1.
  • Equation in slope-intercept form: y=1*x+-4.
