The figure represents a Cartesian plane.
The quadrant in which Q is found is:
1st quadrant.
4th quadrant.
3rd quadrant.
2nd quadrant.
On the Cartesian plane, the line y = 0 is called the:
y-axis.
Ordinate.
x-axis.
Origin.
The midpoint of the line segment joining the points P(6, - 3) and Q(18, 15) is the point with coordinates:
(- 6, - 9).
(- 6, 6).
(12, 12).
(12 ,6).
The gradient of the line 2y - 4x = 3 is:
2.
4.
-2.
-4.
The lines with equations y = m₁x + c and y = m₂x + k are perpendicular if:
m₁m₂ = -1.
m₁m₂ = 1.
m₁ = m₂.
2m₁ = m₂.
