Question 8:
Your choice is correct: two figures are similar if all correspondant sides are in the same ratio.
In your case, the figure on the right have correspondant sides which are all three times the figure on the left, since

So, the two figures are similar and their ratio is 1:3.
Question 9:
We follow exactly the same approach: let's see if the radii and the heights are in the same ratio: the radii are in ratio

While the heights are in ratio

So, the answer is again yes, they are similar, and the ratio is 1.6.

Which one do you want me to answer?
Answer:
The x-intercept is (-2,0)
The y-intercept is (0,3)
Step-by-step explanation:
An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

So, the x-intercept is (-2,0).
Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

Thus, the y-intercept is (0,3).
