Answer 2

Answer:

1) b) 4

given, (4,19)

so, y=ax+3

19-3=4a

a=16/4

a=4

2) c) 2

given (a,4)

so, 3x+y=10

3a=10-4

a=6/3

a=2

3) a) (2,0)

because here y-axis will be zero and x-axis will be 2 so the line will pass through x-axis

4) d) infinitely many

because you can change the coefficient of both x and y, so the output will also be changed

5) b) a point

because there is no y-axis is given, if it's given then the answer will defer on how much y-axis is given...

Hope you may get it
