Find the equation of a line which passes through point (7,-7) and is parallel to the line formed by the equation y = -x - 4. Express it in slope-intercept form.
\n" ); document.write( "-----
\n" ); document.write( "y = -x-1 is in slope-intercept form y = mx + b
\n" ); document.write( "--------------
\n" ); document.write( "The slope of y = -x - 4 is -1
\n" ); document.write( "Parallel lines have the same slope.
\n" ); document.write( "Use y = mx + b and the point to find b, the y-intercept
\n" ); document.write( "-7 = -1*7 + b
\n" ); document.write( "b = 0
\n" ); document.write( "--> y = -x
\n" ); document.write( "=======================
\n" ); document.write( " Find the equation of a line which passes through point (-7, 1) and is parallel to the line formed by the equation y = 6x + 8. Express it in slope-intercept form.
\n" ); document.write( "Same as above.
\n" ); document.write( "-----------------
\n" ); document.write( " Find the equation of a line which passes through point (-2, -7) and is parallel to the line formed by the equation y = 5x + 4. Express it in slope-intercept form.
\n" ); document.write( "Same as above.
\n" ); document.write( "-----------------
\n" ); document.write( " Find the equation of a line which passes through point (-2, 3) and is parallel to the line formed by the equation y = 4x + 7. Express it in slope-intercept form.
\n" ); document.write( "Same as above.

\n" ); document.write( " Find the equation of a line which passes through point (6, 8) and is perpendicular to the line formed by the equation y = 6x + 1. Express it in slope-intercept form.
\n" ); document.write( "The slope of the given line is 6.
\n" ); document.write( "The slope of perpendicular is the negative inverse = -1/6.
\n" ); document.write( "Use that, same as #1 above.
\n" ); document.write( " \n" ); document.write( "
