    well for the first attachment u have u look at ur answers and try to match it up cuz with the muliple choice it either A. give all fase and 1 true or B. give u the correct one and gives u mixed up mumbo jumbo.

    so for example the answer choice A is y^2=1-3x well -3x is in the correct slot but 1 is not so thats not the answer so for By^2=-3-x well x is 0 so that means that there is no -3 in its y slot to created a y^2 for C y^=x+1 there is a x and tere is a 1 in the y slot beside the x so look theres one answer thats may be it and D y^2=x-3 there is a x but in the y there is no -3 only -2 and -5 so that rules all of the choices but C soo understand a bit better

    I have no clue. Everything your saying is my only example. I dont know how to solve any of this. My book doesnt show anything. But an example I just found says to solve for the origin by the X=0 and the Y2=0 if both are not 0 then the answer is no.

    to find answer of first question *Does the graph of Y2 pass through the origin?* origin is a point when x and y = 0 x=0 y =0 so you can replace x with 0 into y_2 equation if you get 0 for y then yes otherwise answer is no
