when you hear quadratic think x2
when you hear linear think x
when you hear constant think of the integer(number without a variable)
 
Ex: 2x2+3x-9
 2x2 = QUADRATIC term
3x = Linear term
-9 = Constant term
 
y=mx+b is like y=3x+4, so linear term is 3 which is the slope of the "line"(think linear) on a graph and the constant term would then be 4. The 4 is also referred to as the y intercept because thats where it crosses the line on the graph.
 
Its very helpful to graph this stuff out especially if you learn best visually
