Question

Plot the following point on the cartesian plane whose:

abscissa is 3 and ordinate is twice of the abscissa

Answer 1

Given: Abscissa x = 3; Ordinate y = twice the abscissa (y = 2x).

Step-wise calculation:

1. y = 2 × x

2. y = 2 × 3 = 6

The point is (3, 6). To plot it: from the origin go 3 units to the right (x = 3) and 6 units up (y = 6), then mark the point (3, 6).
