Question

If (a, 1) lies on the line represented by equation 3x + y = 10 ,then the value of a is

Answer 1

Answer:

The value of a is 3.

Step-by-step explanation:

Given coordinate = (a,1)

Therefore, abscissa = a and ordinate = 1.   ...(i)

According to the Equation,

3x + y = 10

Substituting the values from (i) in the above equation,

3(a) + (1) = 10

3a + 1 = 10

3a = 10 - 1

3a = 9

a = 3

Hope this helps :)
