Question

if the graph of equation 2x + ky = 10k , intersect x-axis at point (5,0) .find the value of k

Answer 1

x=5 y=0
2(5)+k(0)=10k
10=10k
k=10/10
=1

Answer 2

hey there !

given equation : 2x +ky = 10k

so it passes through (5,0) so this satisfy the equation

=) 2×5 + k×0 = 10k

=) 10 = 10k

=) k = 1
