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

Equation $\"4+x+%2B+1+y+=+3\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-4%2F1\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 3/4 = 0.75.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 3/1 = 3.
Slope is -4/1 = -4.
Equation in slope-intercept form: y=-4*x+3.
