slope between those two points is change in y/change in x, or 3/2
\n" ); document.write( "point slope formula y-y1=m(x-x1), m slope, (x1, y1) one of the points
\n" ); document.write( "y+2=(3/2)(x+1), notice the signs
\n" ); document.write( "y+2=(3/2)x+3/2
\n" ); document.write( "y=(3/2)x-1/2
\n" ); document.write( "---
\n" ); document.write( "same thing
\n" ); document.write( "y-7=3(x-4)
\n" ); document.write( "y=3x-12+7
\n" ); document.write( "y=3x-5
\n" ); document.write( "-------------
\n" ); document.write( "change the sign in front of the h and it is the x-value of the vertex (the y-value is k)
\n" ); document.write( "---------
\n" ); document.write( "the function is moved down 2 units and is much narrower (compressed), increasing three times as rapidly.
