Answer
1) The number 62 gives the value of the temperature (T) when the elevation is exactly at sea level (h = 0).
2) The number -0.003 expresses how much the temperature (T) changes (reduces because of the minus sign) for each increase in elevation (h)
Explanation
The temperature is given as
T = 62 - 0.003h
We can rewrite this in the equation of a straight line form
T = -0.003h + 62
And for a straight line,
The slope and y-intercept form of the equation of a straight line is given as
y = mx + b
where
y = y-coordinate of a point on the line.
m = slope of the line which expresses rate of change of y with respect to x
x = x-coordinate of the point on the line whose y-coordinate is y.
b = y-intercept of the line which gives the value of y when x = 0
By comparing T = -0.003h + 62 with y = mx + c, we see that
m = slope = -0.03
b = y-intercept = 62
Hence, to answer this questions,
1) The number 62 gives the value of the temperature (T) when the elevation is exactly at sea level (h = 0).
2) The number -0.003 expresses how much the temperature (T) changes (reduces because of the minus sign) for each increase in elevation (h)
