Well, we can convert this to the form of a linear equation:
\n" ); document.write( "y=-2x+2
\n" ); document.write( "-2=-2x-y
\n" ); document.write( "2x+y=2
\n" ); document.write( "\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "

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

Equation $\"2+x+%2B+1+y+=+2\"$ describes a sloping line. For any
\n" ); document.write( " 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. 2/2 = 1.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 2/1 = 2.
Slope is -2/1 = -2.
Equation in slope-intercept form: y=-2*x+2.
