Question:
If R = {(2, 1), (4, 7), (1, −2), ...}, then write the linear relation between the components of the ordered pairs of the relation R.
Solution:
Given:
R = {(2, 1), (4, 7), (1, −2), ...}
We can observe that
$1=3 \times 2-5$
$7=3 \times 4-5$
$-2=3 \times 1-5$
Thus, the linear relation between the components of the ordered pairs of the relation R is y = 3x
