You can put this solution on YOUR website!
To graph linear equations, you need to make a table of values. You choose the x and solve the equation for y. Remember you only need to points to define the line, the third is only a check.
\n" ); document.write( "y= -x + 8
\n" ); document.write( "x=0
\n" ); document.write( "y=-(0)+8
\n" ); document.write( "y=8
\n" ); document.write( "x=1
\n" ); document.write( "y=-(1)+8
\n" ); document.write( "y=-7
\n" ); document.write( "x=-1
\n" ); document.write( "y=-(-1)+8
\n" ); document.write( "y=9
\n" ); document.write( "So our points are;
\n" ); document.write( "(0,8);(1,-7);(-1,9)Hope you understand.
\n" ); document.write( "See if you can do the other problem?
\n" ); document.write( "=) \n" ); document.write( "
