Question

if point (2,a) lies on the line 4x-y=3,then a=​

Answer 1

Answer:

a = 5

Step-by-step explanation:

if point (2,a) lies on the line 4x-y = 3

then the coordinates of (x,y) on the line is (2,a) , Hence x = 2 , y = a

Now, put this values in the equation of line

4x - y = 3

4(2)-(a)= 3 = 8-a = 3

-a = 3-8 = -a = 5 , a = 5

Hence the value of a is 5
