You can put this solution on YOUR website!
F(X)=-5x-9
\n" ); document.write( "There doesn't seem to be any limitations to the x values, so the domain is all real numbers.

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation \"5+x+%2B+1+y+=+-9\" describes a sloping line. For any
\n" ); document.write( " equation ax+by+c = 0, slope is \"-a%2Fb+=+-5%2F1\".
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -9/5 = -1.8.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -9/1 = -9.
  • Slope is -5/1 = -5.
  • Equation in slope-intercept form: y=-5*x+-9.
