Question

pleaz select correct option​

Answer 1

Answer:

As the given point (3, 4)

lies on the given line

So,

lt will satisfy the equation of the line

i.e.

When we put x and y co-ordinate of the point in the equation of the line

both will satisfy the equation

So,

$3 \times 4 = a \times 3 + 7 \\ \\ 12 = 3a + 7 \\ \\ 3a = 12 - 7 \\ \\ 3a = 5 \\ \\ a = \frac{5}{3}$

Hence,

option 3rd is correct

Answer 2

Question:-

Given in above attachment↑

Answer :-

→ Option (3) is correct .

Solution :-

If any point (x,y)is on any line then these points will satisfied to this line .

Hence,

points ( 3️⃣,4️⃣) will satisfy to the equation of line 3y = a x + 7,

➡️ 3✖️4 = a✖️3 ➕7

➡️ 12 = 3a ➕7

➡️ 3a = 12 ➖7

➡️ 3a = 5

➡️ a = 5/3

Option (3) is correct.
