Sulla retta a, perpendicolare al piano a, sono stati individuati, da parte opposta rispetto al piano,
due punti A e B. Sul piano è stata tracciata la retta
b, passante per il punto di incidenza H, e su di essa
è stato individuato un punto C distante 20 cm da
H. Se il segmento AB è lungo 36 cm ed è diviso dal
7
punto H in due parti tali che AH = di HB, quanto
misurano i segmenti AC e BC? [29 cm; 25 cm]

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
