Question

determine whether the point (2, 5) lies on the graph of the equation 3x - y = 1 or not.

Answer 1

Answer:

given x=2& y=5. as point (x,y)=(2,5)

Step-by-step explanation:

substitution method

• 3x-y=1
• 3(2)-5=1
• 6-5=1
• 1=1

so lhs is equal to rhs

so (2,5) is a point lies on the graph of the equation 3x-y=1

Answer 2

Answer:

given:point (x,y)=(2,5)

:.x=2 &y=5

Step-by-step explanation:

solution:by using substitution method

substituting the value point (2,5)in x & y

3x-y=1

3 (2)-5=1

6-5=1

1=1

so LHS IS EQUAL TO RHS

THEREFORE the point (2,5) lies on the graph of the equation 3x-y=1
