Question

Which of the ordered pairs (0, 0), (–2, 10), (–1, –5), (–3, 9), (5, 1) are solutions for the equation y = 5x?

Answer 1

`(0,0)` and `((-1,-5)`

Explanation:

The rule requires that the first co-ordinate (x) multiplied by 5 must equal the second co-ordinate (y)

This is only true for `x = 0` then `y = 5*0 =0......(0,0)`
and if `x = -1`,

`y =5x-1 = -5. ...............................(-1,-5)`
