find the equation of the line that passing through (-2,4) and having the
\n" ); document.write( "(a) slope of 7/16.
\n" ); document.write( "Use point/slope form: y - y1 = m(x - x1)
\n" ); document.write( "y - 4 = \"7%2F16\"(x - (-2))
\n" ); document.write( "y - 4 = \"7%2F16\"(x + 2)
\n" ); document.write( "y - 4 = \"7%2F16\"x + \"14%2F16\"
\n" ); document.write( "y = \"7%2F16\"x + \"7%2F8\" + 4
\n" ); document.write( "y = \"7%2F16\"x + \"7%2F8\" + \"32%2F8\"
\n" ); document.write( "y = \"7%2F16\"x + \"39%2F8\"
\n" ); document.write( ":
\n" ); document.write( "(b) parallel to the 5x - 3y = 3
\n" ); document.write( "Find the slope, put in the point/intercept form
\n" ); document.write( "5x - 3y = 3
\n" ); document.write( "-3y = -5x + 3
\n" ); document.write( "y had to be positive, mult both sides by -1
\n" ); document.write( "3y = 5x - 3
\n" ); document.write( "Divide both sides by 3
\n" ); document.write( "y = \"5%2F3\"x + \"3%2F3\"
\n" ); document.write( "y = \"5%2F3\"x + 1
\n" ); document.write( "slope = \"5%2F3\", parallel lines have the same slopes, us the point slope form
\n" ); document.write( "y - 4 = \"5%2F3\"(x - (-2))
\n" ); document.write( "y - 4 = \"5%2F3\"(x + 2)
\n" ); document.write( "y - 4 = \"5%2F3\"x + \"10%2F3\"
\n" ); document.write( "y = \"5%2F3\"x + \"10%2F3\" + 4
\n" ); document.write( "y = \"5%2F3\"x + \"10%2F3\" + \"12%2F3\"
\n" ); document.write( "y = \"5%2F3\"x + \"22%2F3\"
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "(c) passing through the origin
\n" ); document.write( "slope = \"4%2F%28-2%29\" = -2
\n" ); document.write( "y = -2x is the equation passes thru 0,0 and -2,4
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "(d) parallel to the y-axis.
\n" ); document.write( "x = -2
\n" ); document.write( "
\n" );
