Question

8. Find the value of a so that the point (3, a), lies on the line represented by 2x-3y = 5​

Answer 1

Step-by-step explanation:

If a point (x1,y1) is said lie on a line represented by ax+by+c=0 , then the given equation of a line should hold true when the values of the coordinates of the points are substituted in it .

Here it is said that the point (3,a) lies on the line represented by the equation 2x-3y-5=0

substituting the coordinates of the values in the equation of the line we have,

2x-3y-5=0

2(3)-3(a)-5=0

-3a= 5-6

-3a= -1

a= -1/-3

a=1/3

thus , the value of 'a' satisfying the given condition is a=1/3

HOPE THIS IS HELPFUL FOR YOU.
