First, we write in a cell the function we want to represent, for example: y=-3x+1.2. Then, we put x in a cell below the function and just at the left, y. From those cells we´ll make data columns for the variables x and y. 3. We give numbers to the x column, for example from 0 to 10, and then fe apply the formula in the y column. Imagine the first y is in the cell C5, we´d put in it =-3*D5+1 and then we´d extend the formula to apply it to the entire document. 4. Finally, we’d have to represent it graphically. To do it, we select the y column, then press ctrl and select the x column, and we choose the type of graph we want, for example the point graph. https://padlet.com/pintor_r/2iueqztp6o6x/wish/155707386 All the steps]]> 2017-02-23 11:30:21 UTC https://padlet.com/pintor_r/2iueqztp6o6x/wish/155707386 https://padlet.com/pintor_r/2iueqztp6o6x/wish/155707396 1.       At first we have to make a table with the two ( incógnitas) , which are X and Y .
 
2.       Then we gave a series of values in X using series 
 
3.       we have to replace the values of X in the function with a formule, and we will have the real values of Y with auto filling.

 

4.       And with the values of X and Y we insert a chart of  ( dispersión )
