Step-by-step explanation:
b) if (3,9) then x = 3 and y = 9
9=2(3)+3
9=9
since LHS= RHS , b) (3,9) lies on the line
2. y=3x+4
if d) (4,12)
then, x =4 and y = 12
12=3(4)+4
12=16
since LHS≠RHS , (4,12) does not lie on line
Answer:
Q.19 : b
Q.20: d
Step-by-step explanation:
In both question just substitute the value of x co-ordinate in the equation to find the answer.
Q19. y = 2x+3
(3,9) y=2*3+3 which is y=6+3 = 9 for other options this will not match with coordinate given.
