Question

I need help on this question can anyone explain to me the answer?

Answer 1

Option C,
`y = (1)/(10) x+1`

Explanation:

We can find the correct answer by plugging in the x and y values of a point on the graph into each option, then finding the one that gives a true statement as a result.

For example, one point on the graph is (30,4). We can substitute 30 for the x and 4 for the y in option C's equation,
`y = (1)/(10) x+1`. Then, simplify:

`y = (1)/(10) x+1\\4 =(1)/(10) (30)+1\\4 = (30)/(10) +1\\4 = 3 +1\\4 = 4`

4 does equal 4, so when we substitute a point from the graph into this equation, the result is a true statement. Thus, option C is the answer.
