Algebra.Com's Answer #343888 by lwsshak3(11628) ![]() You can put this solution on YOUR website! I always end up with the slope upside down because I get confused which one equals x or y. g(x), or x. Like if the problem is f(6)=7 and f(3)= 2 I get confused on which one is x and y. Is the slope 3/5? Or 5/3? How can I remeber which one it is? \n" ); document.write( "** \n" ); document.write( "f(6)=7 says that if you plug in an x value of 6 into the equation, you will get a y-value of 7. \n" ); document.write( "In other words, this is another way to write an ordered (x,y) pair like (6,7) \n" ); document.write( "f(3)=2 represents an ordered pair of (3,2) \n" ); document.write( ".. \n" ); document.write( "Slopes are defined as a change in y/change in x \n" ); document.write( "Some ways of writing slope=∆y/∆x=rise/run=(y1-y2)/(x1-x2) \n" ); document.write( ".. \n" ); document.write( "Hope this clears up some confusion you have about functional notation and slopes. \n" ); document.write( " |
