Answer:
x can be any value, x will be the input, y will be the output.
Step-by-step explanation:
If x = 3, If x = 6, If x = 9,
y = 5x - 4
y = 5 (3, 6, or 9) - 4
y = 11, y = 26, y = 41.
These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.
X (Input) I Y (Output)
3 I 11
6 I 26
9 I 41
See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.
Hope This Helps! :)
