1. graph the equation and identify the y-intercept. x + 5y = 20
\n" ); document.write( "At the y-intercept, x = 0
\n" ); document.write( "0 + 5y = 20
\n" ); document.write( "y = 4
\n" ); document.write( "------------------
\n" ); document.write( "2. The valve, v, of a shopkeeper's inventory software program is given by v = -1/2t + 6, where t is the number of year's since the shopkeeper bought the program. What is the program worth 4 years after it is first purchased?
\n" ); document.write( "Plot the point with the given t-valve, 4.
\n" ); document.write( "v(t) = -t/2 + 6
\n" ); document.write( "v(4) = 4
\n" ); document.write( "-----------------------
\n" ); document.write( "3. Find the y-intercept and x-intercept for the equation 3x + 2y = 12 What is the y-intercept? Type an ordered pair.
\n" ); document.write( "Do it like #1.
\n" ); document.write( "-------------------
\n" ); document.write( "4. Find the intercepts and then use them to graph the equation 3y - 9 = 3x
\n" ); document.write( "Similar to #1.
\n" ); document.write( "-------------------
\n" ); document.write( "To graph linear eqns, you need 2 points. Pick values for x or y and find the 2 points. Plot them, and draw a line thru them.
\n" ); document.write( "
\n" ); document.write( "
\n" );
