(iii) y = 2x

Answer 1

Answer:

answer no. D

y = 2x

hope it will help you

Answer 2

Given,

Three equations, y = 2x + c , y = 2x + c and y = 2x.

To find,

Which of the following equations goes through the origin?

Solution,

Any equation of the line that goes through the origin is in the form of y=mx where m is the slope of the equation and the c constant is zero.

• Option ( i )  y = 2x + c and Option ( ii ) y = 2x + c cant go through the origin as it has some value of constant c.

• Option (iii)  y =2x passes through the origin of the line as it is of the form of y = mx where m is a slope that has value 2.

Hence, y = 2x is the correct equation that goes through the origin. (Option iii)
