Learn me up a CARTESIAN PLANE!!

TODAY.... We were all s p a c e d   o u t because, well, its a FRIDAY and were were all ZOMBIES like:

ANYWAYS:

We all practiced and did more work on CARTESIAN PLANES!! We just LOVE our Cartesian planes!! We are (AS I AM TYPING THIS) working on how to get the axis 'Y' coordinates using an EQUATION.

THAT EQUATION IS: Y=MX+B

FOR YOUR INFORMATION:

-Y & X are the Axis' on a Cartesian plane
-M is the amount that the line heads up by or down by
-B is where the line crosses over the Y axis

WE ALSO WATCHED A VIDEO!!!

We are now practicing!
One problem we had to solve was 'What Is The'Y' Coordinates?'...

if..... M=3
         B=5
AND.... The Table is:

                                                           X             Y
                                         1                    ?
                                         3                    ?
                                         5                    ?
                                         7                    ?



*HINT* The Equation is Y=MX+B

      Y=MX+B            Y=MX+B       Y=MX+B      Y=MX+B         
      Y=3(1)+5             Y=3(3)+5        Y=3(5)+5      Y=3(7)+5
      Y=3+5                  Y=9+5            Y=15+5         Y=21+5
      Y=8                       Y=14              Y=20             Y=26


Now we can finish our Table!!


 
                             X           Y
                                        1                 8            
                                        3                 14
                                        5                 20                
                                        7                 26
 NOW WE CAN FILL OUT OUR CARTESIAN PLANE!!!!!!!!!
 
*I can't do this virtually so... sorry :(
