The freezing point of water, T (measured in degrees fahrenheit), at altitude a (measured in feet) is modeled by the function T(a)= .0001a+32. In terms of altitude and temperature, which statement describes the meaning of the slope

Question options:

The boiling point increases by 18 degrees as altitude increases by 1000 feet

The boiling point increases by 1.8 degrees as the altitude increases by 1000 feet

The boiling point decreases by 18 degrees as the altitude increases by 1000 feet

The boiling point decreases by 1.8 degrees as the altitude increases by 1000 feet

The freezing point increases by 0.1 degrees for every 1000 feet

Step-by-step explanation:

In the options given we have used it as a reference for our answer. The equation given in terms of temperature and altitude means that for every increase in altitude a(we have assumed here that a increases by 1000 feet each time as in options) there is increase in temperature by 0.1 degrees(freezing point)

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
