\n" ); document.write( "(2,4) and (6,-2).
\n" ); document.write( "First we get the $\"Slope=m\"$ thru Point Slope form:
\n" ); document.write( " $\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$
\n" ); document.write( " $\"m=%28-2-4%29%2F%286-2%29=-6%2F4\"$
\n" ); document.write( " $\"m=-3%2F2\"$
\n" ); document.write( "Then via Slope-Intercept form: $\"y=mx%2Bb\"$
\n" ); document.write( "Thru points (2,4):
\n" ); document.write( " $\"4=%28-3%2Fcross%282%291%29%28cross%282%291%29%2Bb\"$
\n" ); document.write( " $\"4=-3%2Bb\"$ -----> $\"b=4%2B3=7\"$ Y-intercept
\n" ); document.write( "Thru points (6,-2):
\n" ); document.write( " $\"-2=%28-3%2Fcross%282%291%29%28cross%286%293%29%2Bb\"$
\n" ); document.write( " $\"-2=-9%2Bb\"$
\n" ); document.write( " $\"b=-2%2B9=7\"$
\n" ); document.write( "*THEY SHOULD BE EQUAL which is good.
\n" ); document.write( "So,via Slope intercept form: $\"highlight%28y=%28-3%2F2%29x%2B7%29\"$ Answer
