Which of the following pairs of points both lie on the line whose equation is 3x-y=2?

Question

3,-2 and 1,5

2,4 and 3,7

2,4 and 1,5

2,-2 and 1,5

3,7 and 3,-2

Answer 1

The easiest way to solve this is to draw the line and see if the points are on the line

To draw the line find the x and y axis

for the x axis y is zero so 3x =2

divide both sides by 3 and the x axis is 2/3 on the horizontal  line 2/3 of a point from the middle draw a dot

Now to get the y axis x is zero so -y=2

divide both sides by -1 and you get y = -2

on the vertical line go two down from the middle and draw a dot

Now connect the dots and continue on both sides

Now plot all the points and see witch ones fall on the line

Good luck
