how to find an equation for the line parallel to the line -3x+9y=-9 having the same y-intercept as 4x-9y=8
\n" ); document.write( "-3x+9y=-9
\n" ); document.write( "We have to find the slope so we have to get the formula in this form: y=mx+b where m is the slope.
\n" ); document.write( "9y=3x-9
\n" ); document.write( "y=(1/3)x-1
\n" ); document.write( "so, m=1/3 and any line parallel to it will have m=1/3.
\n" ); document.write( "the line must have the same y intercept as 4x-9y=8
\n" ); document.write( "x intercept is when y=0. When that happens 4x=8; x=2
\n" ); document.write( "now we have a point: (2,0) and a slope: 1/3.
\n" ); document.write( "\"y-y%5B1%5D=m%28x-x%5B1%5D%29\"
\n" ); document.write( "\"y-0=%281%2F3%29%28x-2%29\"
\n" ); document.write( "\"y=%281%2F3%29x-%282%2F3%29\" is the formula.
