Question

the point which lies on the line y = 2x is?

a) (-2,-6)
b) (2,-4)
c) (-5,-10)
d) (-5,10)​

Answer 1

Answer:

c is your answer my frnd and hi to all. you only need to substitute x and y (x,y). so x=-5 y will be equall to -10

Answer 2

Answer:

The correct answer is option (c).

Explanation:

To find whether the point lies on the line , we just have to substitute the values of points on the place on x and y in the equation and if it satisfies on both sides, the point will lie on the line.

in this , we will check one by one .

a) (-2,-6)

we will place -2 in the place of x and -6 in the place of y and check whether it will satisfy or not.

y = 2x

-6 in LHS =2 (-2) in RHS

RHS = -4

LHS ≠ RHS

b) (2,-4)

we will place 2 in the place of x and -4 in the place of y and check whether it will satisfy or not.

y = 2x

-4 in LHS =2 (2) in RHS

RHS = 4

LHS ≠ RHS

(c) (-5,-10)

we will place -5 in the place of x and -10 in the place of zy and check whether it will satisfy or not.

y = 2x

-10 in LHS =2 (-5) in RHS

RHS = -20

LHS = RHS

These points are satisfying the equation.

(d) (-5,10)

we will place -5 in the place of x and 10 in the place of y and check whether it will satisfy or not.

y = 2x

10 in LHS =2 (-5) in RHS

RHS = -4

LHS ≠ RHS

So the correct option is (C).
