### 5 Questions

Q1.

John says, "In my line, all my y-ordinates are triple my x-ordinates". Tick the equation that represents John's line.

y = 4x

y = x - 3

y = x +3

Q2.

Jenny says, "In my line, all my y-ordinates are 5 less than my x-ordinates". Tick the equation that represents Jenny's line.

y = 5 - x

y = 5x

y = x + 5

Q3.

Which of the following lines does the point (2,6) lie on?

y = 2x

y = x - 4

y = x +3

Q4.

Which of the following lines does the point (3,-6) lie on?

y = 2x - 4

y = 3x

y = x + 8

Q5.

Which of the following coordinates lies on the line y=2x-1

(2,5)

(3,7)

(6,5)
