The slope-intercept form of a line is \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( " \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( " \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( " \n" ); document.write( "(0,2)+(1,-1.35)=(1,0.65) \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
