You can put this solution on YOUR website!

\n" ); document.write( "First put this equation into slope-intercept form. (y=)
\n" ); document.write( "-3x - 4y = -12 ------add 3x to each side.
\n" ); document.write( "-4y = 3x - 12 -------divide each side by -4
\n" ); document.write( "\"y+=+-%283%2F4%29x+%2B+3\"
\n" ); document.write( "Your y-intercept is the last number in the slope-intercept equation. In this case it is 3.
\n" ); document.write( "To find the x-intercept, the y point is 0. So you would fill in a 0 for the y value.
\n" ); document.write( "-3x - 4y = -12
\n" ); document.write( "-3x - 4(0) = -12 -----fill in a zero for y
\n" ); document.write( "-3x - 0 = -12 ---------(-4)times 0 is zero
\n" ); document.write( "-3x = -12 -------------The 0 can be taken out.
\n" ); document.write( "x = 4 ---------------divide by -3 and get 4
\n" ); document.write( ".
\n" ); document.write( "y-intercept = 3
\n" ); document.write( "x-intercept = 4
\n" ); document.write( "\"graph%28350%2C250%2C-7%2C7%2C-7%2C7%2C-.75x%2B3%29\"
\n" ); document.write( ".
\n" ); document.write( "Tip: If you didnt want to put your equation into slope-intercept form, then you could fill in a 0 for the x-value, to find the y-intercept and solve it that way like we did for the x-intercept.
\n" ); document.write( ".
\n" ); document.write( "To find the slope, m, you would need 2 point. You could use your intercepts for this
\n" ); document.write( "X(4,0)
\n" ); document.write( "Y(0,3)
\n" ); document.write( "x1=4 ; y1=0
\n" ); document.write( "x2=0 ; y2=3
\n" ); document.write( "\"m=%28y2-y1%29%2F%28x2-x1%29\"
\n" ); document.write( "\"m=%283-0%29%2F%280-4%29\"
\n" ); document.write( "\"m=%283%29%2F%28-4%29\"
\n" ); document.write( "\"m=%28-3%2F4%29\"
\n" ); document.write( ".
