Answer: OPTION A.

Step-by-step explanation:

By definition:

- When you reflect a figure, you flip it over a line of reflection, then, both figures will be in opposite directions.

- The image (which is the reflection) and the pre-image will have the same shape ad size.

- If a figure is reflected over the y-axis, then the sign of the x-coordinate is changed.

Keeping the above on mind, you can conclude that when a triangle is reflected over the y-axis the coordinates of the vertices are afectted as following:

- The y-coordinate is not changed.

- The sign of the x-coordinate is changed.

Then:

$(x,y)$ → $(-x,y)$

What is the slope of this line

ohaa [14]

Slope-intercept form is given by y = mx + b. m represents the slope of the equation, and b represents the y-intercept.

m = 10.322

The slope is 10.322.

What is the interquartile range (IQR) of the following data set 17 16 21 15 25 22 18 23 17

Pepsi [2]

IQR = 6

First locate the median $Q_{2}$ at the centre of the data arranged in ascending order. Then locate the lower and upper quartiles $Q_{1}$ and $Q_{3}$ located at the centre of the data to the left and right of the median.
