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

Equation $\"0.15+x+%2B+-1+y+=+28\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-0.15%2F-1\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 28/0.15 = 186.666666666667.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 28/-1 = -28.
Slope is -0.15/-1 = 0.15.
Equation in slope-intercept form: y=0.15*x+-28.
