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?
