Question

If the point A(a,b)and B(b,0) lie on the linear equation y=8x+3. Find the value of a and b

Answer 1

Answer:

The given linear equation is;

y = 8x + 3.

It is given that;

Points A(a,b) and B(b,0) lies on the given equation, thus both the points would satisfy the equation.

Now,

Since, the point A(a,b) satisfy the equation, thus;

=> y = 8x + 3

=> b = 8a + 3 --------(1)

Also,

Since, the point B(b,0) satisfy the equation, thus;

=> y = 8x + 3

=> 0 = 8b + 3

=> 8b = -3

=> b = -3/8 --------(2)

Now,

Putting b = -3/8 in eq-(1), we get;

=> b = 8a + 3

=> -3/8 = 8a + 3

=> 8a = -3/8 - 3

=> 8a = (- 3 - 24)/8

=> 8a = -27/8

=> a = -27/64

Hence,

The required values of a and b are

-27/64 and -3/8 respectively.
