Question

Y=2x+5, and the point (3,k) lies on this line. determine the value of k?

Answer 1

$Given \:linear \:equation \: y = 2x + 5 \:--(1)$

$and \:Point \: (3,k) \: lies \:on \:this \:line.$

$Now, substitute \: x = 3, \:and \:y = k \: in \\equation \:(1) , we \:get$

$k = 2\times 3 + 5$

$\implies k = 6 + 5 = 11$

Therefore.,

$\red{ Value \:of \:k } \green {= 11 }$

Answer 2

Answer:

11

Step-by-step explanation:

here (3,k) are given points

x=3

y=k

substute x and y values in y=2x+5

k=2(3)+5

k=6+5

k=11
