Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc

Equation $\"4+x+%2B+2+y+=+8\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-4%2F2\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 8/4 = 2.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 8/2 = 4.
Slope is -4/2 = -2.
Equation in slope-intercept form: y=-2*x+4.

\n" ); document.write( "\n" ); document.write( "In this case, you quite simply create a linear equation and solve. To help you avoid overloading yourself, here is the equation you would use: y=4x-3. y represents what the number of waste sites in washington is. X represents the number of waste sites in california. When you solve out the equation, x is equal to 171. \n" ); document.write( "
