1-¿Quién ha estado ahí?
2-¿Qué representa esa pirámide del estado de Yucatán?​

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

Does the problem say y=x+4?
