Function p is a linear function with a y-intercept of 5.function q is defined by the equation y=-1/3x +4.what statement must be true about functions p and q

You don't have answers here, but there are only a few things that are inherently true here.

Firstly, we know that they don't share a y intercept.

Secondly, we know that there must be one intersection of the two functions, unless of course P also has a -1/3 slope. Then there are 0 intersections. 

Apart from that, there is little to be concluded. 

Ithink is a. true, but not sure
