Question

(1) The solution of x - 2 = 0 represents dash on the number line.

(2)If the point (1, -2) is on the line x - 2y + k = 0 then find the value of k. Write the equation of the line passing through the point (0,4) and parallel to X-axis. ​

Answer 1

Answer:

1.x-2=0, 2+0=2,then x=2

2.the number lies between 1&-2 are -1,0

x-2y+k=0,x+k=2.
