Question

suppose a rectangular button within a ui is positioned so that its upper-left corner is at a location described as 100, 320. the value 320 ______
○ a. indicates that the upper-left corner of the button is 320 units from the bottom of the screen
○ b. indicates that the upper-left corner of the button is 320 units from the left side of the screen
○ c. is the y-coordinate
○ d. is the x-coordinate

Explanation:

In UI positioning, coordinates are typically in (x, y) format where x is horizontal (left - right) and y is vertical (top - bottom or bottom - top depending on the system, but the second value in (100, 320) is the y - coordinate. Option a is wrong as usually y - coordinate is from top (or has a specific origin), option b is for x - coordinate (100 would be x for left - right), option d is wrong as 320 is not x - coordinate. So 320 is the y - coordinate.

Answer:

c. is the y - coordinate
