Coding in Scratch Part I

When you see a mathematical expression as (5, -2) to denote the location in the screen, what is the value of X in the series?

• 5

• -2

• 0

• none of the choices

The first quadrant of an area of a square is located at the upper right quarter. How are the values of X and Y represented in these locations?

• +, +

• +, -

• -, -

• • -, +

If we move from 0 to the left of the X line, the sign of the numbers becomes -

• positive

• negative

• zero

• no sign

The intersection of the X and the Y lines in the Scratch stage has a value of -

• positive

• negative

• zero

• none of the choices

Which of the following lines denotes the x axis?

• the horizontal line

• the vertical line

• the unseen diagonal line

• both horizontal and vertical lines

Which of the lines as shown in the image denotes the Y axis?

• the horizontal line

• the vertical line

• the unseen diagonal line

• both the horizontal and the vertical line

When you want to display a Sprite in the Scratch stage, its default position is at what location?

• the X axis

• the Y axis

• 0 (number zero)

• depending where you'd like it to appear

Supposing I want to let my Sprite appear above the middle line of the stage, which axis shall I put a value on in the script?

• X axis

• Y axis

• both

• none of the axis

Supposing I want to let my Sprite appear on the left part of my screen, which axis shall I specify a value on?

• X axis

• Y axis

• both

• none

If I need to place the Sprite in the lower part of the screen, without considering a diagonal position, which of the following values shall I specify in the script?

• a positive X value

• a negative X value

• a positive Y value

• a negative Y value
