Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation 3+x+%2B+-3+y+=+9 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+-3%2F-3.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 9/3 = 3.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 9/-3 = -3.
  • Slope is -3/-3 = 1.
  • Equation in slope-intercept form: y=1*x+-3.
