Graph the functions: f(x) = -2x - 5.
\n" ); document.write( ":
\n" ); document.write( "y = f(x)
\n" ); document.write( ":
\n" ); document.write( "y = -2x - 5
\n" ); document.write( ":
\n" ); document.write( "Choose some values for x. Substitute for x in the equation and solve for y.
\n" ); document.write( "Good range is from -3 to + 3. Since it is a linear equation (a straight line),
\n" ); document.write( "two plots will do, however a third plot will point out a mistake and more will
\n" ); document.write( "give you some practice.
\n" ); document.write( ":
\n" ); document.write( "Here is x = -3 as an example:
\n" ); document.write( "y = -2x - 5
\n" ); document.write( "y = -2(-3)
\n" ); document.write( "y = +6 - 5
\n" ); document.write( "y = +1
\n" ); document.write( ":
\n" ); document.write( "Do the same for x = -1 to x = +3, the table should look like this
\n" ); document.write( "x | y
\n" ); document.write( "------
\n" ); document.write( "-3|+1
\n" ); document.write( "-1|-3
\n" ); document.write( " 0|-5
\n" ); document.write( "+1|-7
\n" ); document.write( "+2|-9
\n" ); document.write( "+3|-11
\n" ); document.write( ":
\n" ); document.write( "Plot these coordinates, choose a scale that will include all these values,
\n" ); document.write( "your graph should look like this:
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-8%2C+8%2C+-12%2C+10%2C+-2x+-+5%29+\"
\n" ); document.write( ":
\n" ); document.write( "Study this and see how the x|y coordinates agree with this graph and it will all
\n" ); document.write( "make sense to you. \n" ); document.write( "
\n" );
