Answer: the answer is b
Step-by-step explanation:
Given two points, the equation of the line may be determined by,
y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)
Substituting the given values,
y - 7 = ((9 - 7) / (6 - 3))(x - 3)
Simplification will yield to an answer of,
y = 2x/3 +5
Thus, the answer is the second choice.
hope this helps :)

Hello!
First off, (-inf, -2) was half of the domain, so you were right on track, but almost there!
Since this function has a vertical asymptote at x = -2, any x-values that are equal to -2 cause the function to be undefined. So, we show that as (-∞, -2) because this function is a continuous function from that interval.
Since this function is also continuous from the interval -2 to ∞, we show that as the second part of our domain; written as (-2, ∞).
Remember that parentheses and brackets have different meanings when using them to state the domain/range of a function. Parentheses are used to <u>not</u> include that value, while brackets are used <u>to</u> include it.
In that case, we need to combine this two intervals using the "union" symbol, which is "U".
Therefore, the domain of the function is (-∞, -2) U (-2, ∞).
