The factor pairs of a number when multiplied give the original number.
Therefore, all the factor pairs of 28 are:

The correct choice is the first one
The slope of function A is the coefficient of x, which is 6.
The slope of function B is the rise divided by the run, which is 3/1 = 3.
The appropriate choice is ...
... c) Slope of Function A = 2×Slope of Function B
I mean I think so I’m not completely sure it’s a really hard question
256 is the answer. I know this because 128+128 equals 256.
