Question

express y in the terms of x from the equation 3x+2y = 8 and check whether the point (4,-2) lies on the line

Answer 1

3x+2y=8

2y= 8-3x

y= (8-3x)/2

Now put x= 4 and y= -2 in the above equation.

LHS = -2

RHS= (8-3(4))/2 = (8-12)/2 =- 4/2=-2

since lhs=rhs so the point (4,-2) lies on the line

Answer 2

Answer:

Step-by-step explanation:

3x+2y=8

2y= 8-3x

y= (8-3x)/2

Now put x= 4 and y= -2 in the above equation.

LHS = -2

RHS= (8-3(4))/2 = (8-12)/2 =- 4/2=-2

since lhs=rhs so the point (4,-2) lies on the line
