Both graphs A and B are linear. In both graphs, the y value is going up at a constant rate in comparison to their x values. For example, in graph A every time the x value is increased by 1 the y value is increased by 2 values showing that they have the same gradient. For a graph to be linear it must have a constant rate of increase or decrease.
The answer is 5. This can be found using the two points given ( (0,0) and (3,15) ) and using the slope formula (15-0 divided by 3-0)
20.75 is the answer

Answer: A
Step-by-step explanation:
Note that 13 times 4 is 52.
Note also the log rule for multiplication: log ab=log a + log b.
Thus, log 4 + log 13 = log 52.
