Question

Find the value of k if x = 2 and Y =1 is a solution of the equation (K - 2) X + 4 Y= 10 and have the graph of the equation write the coordinates of the point where the graph cuts the y-axis

Answer 1

Putting x=2 and y=1 in (K - 2) X + 4 Y= 10,

(k-2) 2 + 4* 1 = 10

2k - 4 + 4 = 10

2k = 10

k = 10/2 = 5
