Slope of (5a, b) and (2a, 2b)

You cannot find a number answer as there has been no value given to a or b. So 2a + 5a + a = 8a, b + b + 2b = 4b, simplified you get 8a+4b.

8a+4b

Step-by-step explanation:

i think is g(1)=-1.

hope that i can

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
