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

Equation $\"7+x+%2B+1+y+=+0\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-7%2F1\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 0/7 = 0.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 0/1 = 0.
Slope is -7/1 = -7.
Equation in slope-intercept form: y=-7*x+0.
