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

Equation $\"-2+x+%2B+1+y+=+5\"$ 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. 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.
