First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.

-5+3y=-4
+5 +5

3y= 1

Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.

Answer:The answer is C

Step-by-step explanation:

Because what we have in x^2, the y value can never be negative, no matter what the x value is. When it is squared, it will always remain positive. Because there is a y intercept of 1, and x cannot be negative, you can only go up form one. So therefore, all of the y values have to be greater than or equal to one.
