X Y
\n" ); document.write( "-3 7
\n" ); document.write( "-2 4
\n" ); document.write( "-1
\n" ); document.write( "0
\n" ); document.write( "1
\n" ); document.write( "2 -8
\n" ); document.write( "3
\n" ); document.write( "Use the first two pairs to create the equation: y = mx + b:
\n" ); document.write( "Assign as follows:
\n" ); document.write( "x1=-3, y1=7
\n" ); document.write( "x2=-2, y2=4
\n" ); document.write( ":
\n" ); document.write( "Find the slope m: \"%284-7%29%2F%28-1-%28-2%29%29\" = \"%28-3%29%2F1\" = -3
\n" ); document.write( "Use the point/slope form: y - y1 = m(x - x1)
\n" ); document.write( "y - 7 = -3(x - (-3))
\n" ); document.write( "y - 7 = -3x - 9
\n" ); document.write( "y = -3x - 9 + 7
\n" ); document.write( "y = -3x - 2: the equation we want
\n" ); document.write( ":
\n" ); document.write( "Substitute the given x values and find y, to complete the table
\n" ); document.write( "x=-1
\n" ); document.write( "y = -3(-1) - 2
\n" ); document.write( "y = 3 - 2
\n" ); document.write( "y = 1
\n" ); document.write( "the x/y pair -1,+1
\n" ); document.write( "x = 0
\n" ); document.write( "y = -3(0) - 2
\n" ); document.write( "y = -2
\n" ); document.write( "the pair 1,-2
\n" ); document.write( ":
\n" ); document.write( "the table now looks like this
\n" ); document.write( "X Y
\n" ); document.write( "-3 7
\n" ); document.write( "-2 4
\n" ); document.write( "-1 1
\n" ); document.write( "0 -2
\n" ); document.write( "1
\n" ); document.write( "2 -8
\n" ); document.write( "3
\n" ); document.write( "check our equation using x=2, then
\n" ); document.write( "you can do the same with x = 1 and x = 3, to finish the table
