→OUTPUT
(i) The input is 45.
What is the output? [1]
(ii) The output is 0·9.
What is the input? [1]
(b)

This number machine can be used to find coordinates \((x, y)\).

\(x\)→Multiply
by 4
→Add 1→\(y\)
(i)

Use the number machine to complete these coordinates. [3]

(2, ………)   (0·5, ………)   (−1, ………)   (………, 5)

(ii)

These coordinates can be used to draw a straight line.

Plot the coordinates found by the number machine and draw the line. [3]
