You can put this solution on YOUR website!
This is more simple than it looks at first glance (aren't you glad?). First graph the line.\r

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"-1+x+%2B+2+y+=+4\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+--1%2F2\".
  • 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 4/2 = 2.
  • Slope is --1/2 = 0.5.
  • Equation in slope-intercept form: y=0.5*x+2.

\n" ); document.write( "\n" ); document.write( "Then simply erase parts of the line in order to dot it. Make sure it is dotted, because if it is not, you are saying that y is less than or equal to...not simply less than. Then, since this inequality is a less than, shade every part of the graph below the now dotted line. Then you're done! Easy, right? \n" ); document.write( "
