If points (ordered pairs) connected by a line are: (0,0), (2,6), (4,12), (6,18) and (8,24) [If you did not make a mistake by typing a point (8,27)], THEN it is a direct proportional relationship in question, defined by formula: y = k*x where k is coefficient of this proportion, and x and y are coordinates of points respectively. So, if you check for EACH point: 0 = k*0, 6 = k*2, 12=k*4, 18=k*6, 24=k*8, for each of these equations, it is obtained for k to has value of 3. And the rule is for a proportion, that has to have SAME k value for each of its points on a line. So the answer is TRUE. But if you did not make a mistake by typing point (8,27), then k value for its equation 27=k*8, will not be 3 as for the rest of the points. And then, the answer would be FALSE, it is NOT a proportional relationship.
The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.
