To find the x- and y-intercepts of -3x-4y=18:
\n" ); document.write( "Two Separate problems to solve!!
\n" ); document.write( "1st To find the x-intercept:
\n" ); document.write( "Let y=0 and solve for x.
\n" ); document.write( "-3x-4*0=18
\n" ); document.write( "-3x=18
\n" ); document.write( "x=18/-3
\n" ); document.write( "x=-6 --> x-intercept is (-6,0)
\n" ); document.write( "2nd To find the y-intercept:
\n" ); document.write( "Let x=0 and solve for y.
\n" ); document.write( "-3*0-4y=18
\n" ); document.write( "-4y=18
\n" ); document.write( "y=18/-4
\n" ); document.write( "y=-9/2
\n" ); document.write( "y=-4.5 --> y-intercept is (0, -4.5)
\n" ); document.write( "To graph, plot the x- and y-intercepts and draw the line!!
\n" ); document.write( "You should also choose an x- or y-value, substitute into the original to find a check point. If your x- and y-intercepts are correct, the point will lie on the line.
\n" ); document.write( "Example: If we let x=1, then
\n" ); document.write( "-3*1-4y=18
\n" ); document.write( "-3-4y=18
\n" ); document.write( "-4y=21
\n" ); document.write( "y=21/-4
\n" ); document.write( "y=-5 1/4
\n" ); document.write( "y=-5.25 --> (1, -5.25) should lie on the line drawn using the intercepts :) \n" ); document.write( "
\n" );
