Question

Line t is graphed in the xy-plane. Line t does not have a y-intercept. Which of the following equations couldrepresent a line parallel to line t?

Answer 1

when a graph doesn't have a y intercept it means that its y value is zero.

The constants in the equations are all intercepts. The only equation whose y is zero and has no constant ( intercept ) is x = 2

Thus, the solution to the question is x = 2 ( because y=o at this point and it has no constant )
