At sea level, the speed of sound in air is linearly related to the air temperature. If it is 35 degrees C, sound will travel at a rate of 352 meters per second. If it is 15 degrees
C, sound will travel at a rate of 340 meters per second. Write a linear equation that
models speed of sound, s in terms of air temperature, T.

your answer is b ^w^ hope i

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
