Question 1

If a vertical and horizontal number line intersect perpendicularly, they form right angles (of
90%) with each other and a co-ordinate system of axes is formed, the horizontal line is called:

[1] Quadrants

[2] y-axis

[3] Co-ordinates

[4] x-axis



Question 2

The point at which the two axes intersect (cross each other) is called:

[1] Centre

[2] Vertex

[3] Origin

[4] Starting point



Question 3

Two lines always intersect each other at

[1] two points

[2] one point

[3] three points

[4] do not intersect each other



Question 4

What is the gradient and the y-intercept for a straight line with the equation y = —2x — 37

[1] Slope = 2, y-intercept = 3

[2] Slope = 2, y-intercept = —3

[3] Slope = —2, y-intercept = —3

[4] Slope = 3, y-intercept = 2


Question 5

A straight line crosses the x-axis at (3, 0) and the y-axis at (0, 2). What is the y-intercept for
this line?
