Answer:
The y-intercept must be zero.
It is possible that the line is horizontal.
Step-by-step explanation:
The description states that the line "crosses both axes at the origin." Â That would mean that the point (0,0) is on the graph. Â The y-intercept is the value of y when x=0. Â We see that it is zero in this case (0,0). Â
The description says nothing about the slope. Â So it could be either positive or negative. Â But it could also mean that the slope is zero. Â A zero slope would be a horizontal line. Â So that is a second statement that is true: Â "It is possible that the line on the graph is horizontal."
