Algebra.Com's Answer #410665 by colliefan(242)![]() ![]() ![]() You can put this solution on YOUR website! The x intercept is the point at which y=0 for an equation. The y intercept is the point at which x=0. Take any of these formulas and substitute 0 in for either the x or the y to determine the intercept.\r \n" ); document.write( "\n" ); document.write( "For example, taking the first equation: \n" ); document.write( "x-3y=9\r \n" ); document.write( "\n" ); document.write( "If x=0 this equation becomes 0-3y=9. Solving for y gives y=-3. For this equation the y-intercept is -3. \n" ); document.write( "For the same equation, if y=0 it becomes: x-3(0)=9, x=9. The x-intercept is 9.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The same thing can be done with the other equations.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
