Graph this equation: 3y-9x=30
\n" ); document.write( "Then must graph this equation.
\n" ); document.write( ":
\n" ); document.write( "Put equation into the slope intercept form y = mx + b
\n" ); document.write( ":
\n" ); document.write( "3y = +9x + 30; added 9x to both sides
\n" ); document.write( "1y = (9/3)x + (30/3); divided equation by 3
\n" ); document.write( "y = 3x + 10
\n" ); document.write( ":
\n" ); document.write( "Substitute for x, -4 to +4 and make a table of x/y coordinates to graph
\n" ); document.write( "Here is x = -4 as an example:
\n" ); document.write( "y = 3(-4) + 10
\n" ); document.write( "y = -12 + 10
\n" ); document.write( "y = -2
\n" ); document.write( ":
\n" ); document.write( " x | y
\n" ); document.write( "--------
\n" ); document.write( "-4 | -2
\n" ); document.write( "-3 |
\n" ); document.write( "-2 |
\n" ); document.write( " 0 | 10
\n" ); document.write( "+1 |
\n" ); document.write( "+2 |+16
\n" ); document.write( "+3 |
\n" ); document.write( "+4 | 22
\n" ); document.write( "I'll let you fill in blanks, find y from the value given of x
\n" ); document.write( ":
\n" ); document.write( "graph should look like this:
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+25%2C+3x+%2B+10%29+\"
