$\"3x%2B4y%3E=17\"$
\n" ); document.write( " $\"4y%3E=-3x%2B17\"$
\n" ); document.write( " $\"y%3E=%28-3%2F4%29x%2B%2817%2F4%29\"$
\n" ); document.write( "Since $\"y\"$ is greater than or equal to the values, shade above the solid line.

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

Equation $\"3+x+%2B+4+y+=+17\"$ describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is $\"-a%2Fb+=+-3%2F4\"$ .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 17/3 = 5.66666666666667.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 17/4 = 4.25.
Slope is -3/4 = -0.75.
Equation in slope-intercept form: y=-0.75*x+4.25.
