Answer:

(8, 5)

Step-by-step explanation:

Let's take a look at the y-intercept, (0, 5). If the axis of symmetry is x = 4, then the distance from (0, 5) is 4 units. If we reflect this point (0, 5) about the axis of symmetry x = 4, the resulting point is (8, 5). In other words, the distance from the y-intercept to the axis of symmetry is 4 units, and so the distance from the y-intercept must be 4 units plus 4 units, or 8 units.

The only answer choice that matches this is the second one: (8, 5).

Which statement about scatter plots is true?

Pie

Answer:

On the Scatter Plot, the two variables associated with each other when represented in Quantitative form that is in the form of x-values and y-values, it can be drawn in two dimensional coordinate plane, Representation being a line.

1.The Line may pass through all the points , a single point or none of the points.

2. It can also predict the future values that is for given x , we can find y and for given y , we can find x.

So, only option (4) which is,Scatter plots can be used to represent quantitative data is true.
