Answer 1

x-intercept: The value of x when f(x)=0 (Set the equation equal to zero and solve for x)
y-intercept: The value of f(x) when x=0 (Replace x with 0 and solve for f(x))

Answer 2

I recommend you do this step by step when telling her how to get the answer
That way she understands it for the test or something

Answer 3

Let's start by finding the x intercept, where f(x) = 0
We have:
\[f(x) = \frac{2}{3}x+4 \\ 0 = \frac{2}{3}x+4\]
Can you solve that for x?

Answer 4

Oooh x-int= -6 & y-int= 4 ???

Answer 5

yes^

Answer 6

Yup.
g(x) = - f(x), which means its the same, but flipped upside down (over the x-axis)
What would flipping the graph do to the x-intercept. The y-intercept?

Answer 7

Not quite. Let's look at a picture to see what happens:
