Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation 5+x+%2B+-2+y+=+9 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+-5%2F-2.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 9/5 = 1.8.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 9/-2 = -4.5.
  • Slope is -5/-2 = 2.5.
  • Equation in slope-intercept form: y=2.5*x+-4.5.
