A resistive touch screen has 5 V applied to the grid in the x-direction and in the y-direction. The screen has 480 pixels in the x-direction and 800 pixels in the y-direction. When the screen is touched, the voltage in the x-grid is 1 V and the voltage in the y-grid is 3.75 V.)
a) Calculate the values of α and ß.
b) Calculate the x- and y-coordinates of the pixel at the point where the screen was touched.
