Question

If the point (2, k) lies on the line 2x + 4y = 8, then find the value of k. (2 marks)

Answer 1

Given,the point (2, k) lies on the line given by the equation 2x + 4y = 8.
Hence, the point(2, k) must satisfy the equation of the given line. (1 mark)
$\Rightarrow$ 2(2) + 4(k) = 8
$\Rightarrow$ 4 + 4k = 8
$\Rightarrow$ 4k = 4
$\Rightarrow$ k = 1. (1 mark)
