On a mountain the temperature decreases by 6.5 for every 1000 meters increase in height. At 2000 meters the temperature is 10. Find the temperature at 6000 meters

the answer is negative 16 degrees or -16 degree s

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
