hejsa :)
15 = a, dvs. hældningen. i dit eksempel betyder det at for hver km. der skal køres, bliver der lagt en afgift på 15 kroner oveni
75 = b, dvs. begyndelses punktet/skæringen med y-aksen. Så i dit eksempel er det en fast afgift transportfirmaet har på, når de skal ud med varer (du ved lige som taxa'er har (; )
Håber du kan bruge hjælpen :)
