Question

If the point
(1, a) lies on the line 4x - y = 5, then the value of 'a' is?​

Answer 1

Answer:

4x - y =5

4 X 1-y=5

4-5=y

-1=y

y=-1

Answer 2

Answer: (-1)

Step-by-step explanation:

In (1,a), 1 is the x-coordinate and a is the y-coordinate.

By substituting the values of x and y in the equation,

4x - y = 5

⇒ 4(1) - a = 5

⇒ 4 - a = 5

⇒ -a = 5 - 4

⇒ -a = 1

⇒ a = (-1)
