The slope-intercept form of a line is \"y=mx%2Bb\" so you know the slope, \"m\", and the y-intercept, \"b\".
\n" ); document.write( "Plot the intercept (0,b).
\n" ); document.write( "The slope gives the change in y, divided by the change in x.
\n" ); document.write( "Here's how to handle it if the slope is a fraction, the slope is an integer, or the slope is in decimal form.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "If the slope is a fraction, take the denominator as a step in x.
\n" ); document.write( "Example:
\n" ); document.write( "\"y=%284%2F5%29x%2B3\"
\n" ); document.write( "You are starting at (0,3) and the slope is (4/5).
\n" ); document.write( "Move 5 places in x.
\n" ); document.write( "You will then move the numerator as the step in y.
\n" ); document.write( "Move 4 places in y.
\n" ); document.write( "(0,3)+(5,4)=(5,7)
\n" ); document.write( "Now you have two points and can plot the line.
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "If the slope is an integer, take 1 step in x.
\n" ); document.write( "Then take the slope as the step in y.
\n" ); document.write( "(0,b)+(1,m)=(1,m+b)
\n" ); document.write( "Now you have two points and can plot the line.
\n" ); document.write( "Example:
\n" ); document.write( "\"y=3x%2B5\"
\n" ); document.write( "(0,5)+(1,3)=(1,8)
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "If the slope is a decimal, follow the previous instructions.
\n" ); document.write( "(0,b)+(1,m)=(1,m+b)
\n" ); document.write( "Now you have two points and can plot the line.
\n" ); document.write( "Example:
\n" ); document.write( "\"y=-1.35x%2B2\"
\n" ); document.write( "(0,2)+(1,-1.35)=(1,0.65)
\n" ); document.write( "
