General feedback
Si es tracta d'una funció lineal, sabem que passa pel punt <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mfenced»«mrow»«mn»0«/mn»«mo»,«/mo»«mn»0«/mn»«/mrow»«/mfenced»«/math»</span> i la seva equació és del tipus f(x) = a·x. Per determinar a només cal imposar que passi pel punt <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mfenced»«mrow»«mi»#a«/mi»«mo»,«/mo»«mi»#b«/mi»«/mrow»«/mfenced»«/math»</span>, és a dir, resoldre l'equació <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»f«/mi»«mo»(«/mo»«mi»#a«/mi»«mo»)«/mo»«mo»=«/mo»«mi»#b«/mi»«/math»</span>.<br />
