1) In which quadrant of the number plane does each point lie?

2) Determine by substitution whether each point lies on the line y = 4x + 7.

3) Find the value of k if (k,7)  lies on the line y = 3x - 5.

4) State whether the following lines increase or decrease from left to right.

5) State the y-intercept of each line.

6) Write down the co-ordinates of the point of intersection of the lines y = 1 and x = -2

7) Find the equation of the line that passes through the point:
