Answer: The answer is (B) They show direct variation because y=x+2 and 10-5=12-7.
Step-by-step explanation: We are given two points (5 7) and (10, 12) and we are to select the correct statement about the two given points.
Since we have
7 = 5 + 2 and 12 = 10 + 2, so we can directly say that the equation of the line passing through the two points will be
y = x + 2.
Since we can directly find the relation between x and y, so we can say that they show direct variation because y=x+2 and 10-5=12-7.
Thus, the correct option is (B).
