Can anyone me answer 4 and 5? plzz

#4

Examine the relationship between y and x, waiting until later to examine the y-intercept.    For example:  If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table.  If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.

Also note that all y values in the table are positive, so a negative slope would be inappropriate.  That eliminates choices A and D.

Focus now on the remaining choices B and C.  Again, let x= 2 and determine the associated y value.  Which y value is closer to the table's 6.5?

B:  0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)

C:  3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)

C is the correct answer.

The slope of the function is 0.5.
