b) unique soluti
23. Alinear equation in two variable has a) infinitely manysolution
c) no solution d) none of these
24. Which of the following pair is a solution of the equation 2x – 3y = 7
a) (5,-1) b) (1,5) c) (0, 2) d) none of these
25. The equation of a line passing through the origin is of the form
a) y = kx b) x + y = k c) x - y = k d) none of these
26. Any point on y axis is of the form
a) (x,0) b) (0, y) c) (y, 0)
d) none of these

Answer 1

Answer:

20)

2x=3/8(y-1)

2x×8= 3(y-1)

16x-3y=-3

then

a=16, b= -3, c=-3

21) x Axis

22) coefficient of y=1
