the table shows the average temperature in january for the cities. according to the table, which statement is correct?
a) barrow is the coldest city in january.
b) fraser is colder than harbin in january.
c) grand fork is the coldest city in january.
d) all of the cities are colder than barrow in january.

Hello there!!

Looking at the table, I can automatically rule out B) and D) because Fraser is -5 degrees and Harbin is -10. Harbin is obviously colder than Fraser in January, so that is incorrect. As for D) you can tell that Barrow is -16 degrees in January. Do the other cities even come close?  Now C) Grand Fork is not the coldest city in January, for Barrow is -16.

In conclusion, your answer would be A) because:

Barrow is the coldest city in January.

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 )
