write in slope-intercept form
\n" ); document.write( ":
\n" ); document.write( "1.a slope -4 and y intercept of 3/4
\n" ); document.write( "The slope intercept form of a line is: \"highlight%28y=mx%2Bb%29\", where m=slope and b=y-intercept.
\n" ); document.write( "In this case, m=-4 and b=3/4, so the equation is:
\n" ); document.write( "\"highlight%28y=-4x%2B3%2F4%29\"
\n" ); document.write( ":
\n" ); document.write( "2.a line passing through (-3,-6) with slope 9/5
\n" ); document.write( "When given a point and a slope, we can find the equation of the line with the point-slope formula: \"highlight%28y-y1=m%28x-x1%29%29\", where m=slope and (x1,y1)=given point
\n" ); document.write( "In this case, m=9/5 and (x1,y1)=(-3,-6)
\n" ); document.write( "\"y-%28-6%29=%289%2F5%29%28x-%28-3%29%29\"

\n" ); document.write( "3.line that passes through (5,2) and m=9/5
