Come si rappresenta l'equazione # y = 2x + 3 #?

The pendenza is #2# e l'intercetta y è #3#. That means that starting point is #(0,3)# e come #x# increases by #1#, #y# increases by #2#. So some points would be:

#(0,3)#, #(1,5)#, #(2,7)#

Plot these three points and draw a line through them:

grafico {2x + 3 [-10.25, 9.75, -2.165, 7.835]}
