im pretty sure it goes up though

sorry i meant altitude

They are directly proportional. (PV=nRT) When the pressure increases, so does the temperature. When the alitude increases, the temperature decreases because the pressure decreases.

No, no, no, no. The P1T1=P2T2 formula is only for ideal gases. You can't use it for our atmosphere. Our atmosphere is not the same temp and it has several different gases in it, so it is not ideal. There is no real formula. Pressure doesn't really affect temperature. However, usually when high pressure is in place, usually the air is more dry because high pressure usually mean clear/sunny. Dry air heats up quite a bit more quickly than humid air (which is usually associated with low pressure). In many cases, at least during the day (when the sun is heating air), high pressure and warm temperatures coincide. There are opposites, though not as common. For example, the tropical depression that hit Britain and France brought warmer temperatures, even though there was pretty low pressure. That's only because it's a tropical system.

Usually high pressure air masses are colder and denser than low pressure masses. The warmer air rises, reducing the air pressure, encouraging convection, and holds more water, so there's a good chance for storms with a low-pressure system. Hurricanes are the extreme example; the air pressure in the core of a hurricane is about the lowest you'll get outside of a lab (and it's a way to measure the storm's intensity; the lower the pressure, the stronger the storm).
High pressure (particularly in the winter), is a cold dense dry mass that squashes most convection, so you'll see very few clouds. Even in the summer, Virginia will often get a "Bermuda High" that will sit nearby, which can cause drought as it suppresses rain and thunderstorms.

In an "Ideal gas", pressure and temperature are directly proportional; as one goes up, so does the other (and vice-a-versa).
But I don't think you are talking about an ideal gas.
I think you're talking about our atmosphere, and if so, there are many other variables involved.

air pressure dosent do anything to the temp........... altitude dose

These two factors are independent.

they are directly proportional ... P1/T1=P2/T2
