    Sorry i got distracted... Okay then first you got to make the equations into standard form.

    Do you know how to make it into standard form?

    Okay then. You have to subtract -2x and 3 to the other side.

    *3y

    So it would be, y=-1+2x and x=4-3y.

    Okay then um i can't explain it well but the number 1 without a variable would be graphed on the y axis (0,1)

    You would then got from (0,1) and go add up to 2 because 2x is not negative. It would then be on (1,1) because you added up to and go right one time.

    Now go back to the start which is (0,1). This is where you'll make another point but it will be in the negative side (really your just reversing what you did so you could make a line). Go down 2 and go left once. (-1,-3)

    We did not solve the 2nd equation but i don't think it's necessary because nothing else matches the 1st equation.

    The solution would be where both lines intersect.

    wait you said its negative so would the answer be A?

    The first point would start at (0,-1) the second point would lie at (1,1)

    The 2nd Equation: x=4-3y

  35. anonymous

    The 1st point would start at (0,4) because 4 is positive and you would go down 3 because 3y is negative so the 2nd point lies in (-1,1)

    Oh i see what i did wrong the 1st equation is plan to see on that graph but i think you have to do something with the 2nd equation. Wait let me figure this out.

    The 2nd equation would be 3y=4-x

    Because a standard form equation starts with a y=
