making linear equation from word problem

An airspeed indicator on aircraft is affected by changes in atmospheric pressure at different altitudes. A pilot can estimate the true airspeed by observing the indicated airspeed and adding it about 2% for every 1,000 feet of altitude.

(a) If pilot maintains a constant reading of 200 miles per hour on the airspeed indicator as the aircraft climbs from sea level to an altitude of 10, 000 feat, write linear equation that expresses true airspeed T (miles per hour) in terms of altitude A (thousands of feet)

(b) what would be the true airspeed of the aircraft at 6,500 feet?
