### 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
Correct answer: 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
Correct answer: y = x - 9
y = x + 8
Q5.
Which of the following coordinates lies on the line y=2x-1
(2,5)
(3,7)
(6,5)
