Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation -2+x+%2B+1+y+=+5 describes a sloping line. For any
equation ax+by+c = 0, slope is -a%2Fb+=+--2%2F1.
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 5/-2 = -2.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 5/1 = 5.
  • Slope is --2/1 = 2.
  • Equation in slope-intercept form: y=2*x+5.

Graph the line and shade in all the area above the line since y is greater than or equal to the y values on the line.
