Question

If a linear equation in x and y reduces to y-b = 0 when x = a , then which of the following is its
solution ?
(a) (a,b) (b) (0,a) (c) (a,-b) (d) (b,0)

Answer 1

Answer:

(a,b)

when x=a then linear equation reduces to y-b=0

so y=b for x=a

(a,b) is a point on the line formed by this linear equation
