You can put this solution on YOUR website!
First get x and y on the same side

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

Equation $\"8+x+%2B+-4+y+=+9\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-8%2F-4\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 9/8 = 1.125.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 9/-4 = -2.25.
Slope is -8/-4 = 2.
Equation in slope-intercept form: y=2*x+-2.25.
