1. ## Graphing Equations

Practice Consider the following.
y2 = -7x

Graph the equation. Find any intercepts. (There may be more than one intercept per axis.)
x-intercept
x-intercept

y-intercept

Find the symmetries, if any. (Select all that apply.)

no symmetries

2. Hi,

A good start would be graphing the equation. It's probably best to slightly re-arrange the equation so y is on the left by itself.

if you can't see the equation straight away, try plotting a few points, you should then see the graph quite easily. The you should see the symmetries etc on the graph.

3. ## Still confused...

How do I actually graph it...put in 0 for x and solve?

4. put in a x, get a y. That's one point. Continue until you think there are sufficient points, and then connect them together with a curve or line.

5. Yes, if you put in x, and work out y and plot this point on a graph.

The put in other values for x, such as 1, 2, 3... and also -1, -2, -3 and find values of y for each of these. If you join up the points you should get a graph. (The graph should be a straight line in your case.)

6. All positive values for x will not give you an answer, start with zero and go into the negatives.

7. Assuming that you mean y^2, the equation will not be a straight line. If you mean 2y, then disregard my previous post.

8. Yes, if you mean y^2 then you will not be able to find solutions to negative values of x!

And, of course, the graph will not be a straight line.

9. Not negative values of x, but negative values on the right side, which only occur if x > 0.

10. now you got me really confused....

11. First, do you mean y^2 as in y squared? I'm going to assume yes.

Then the square of a number is never negative, so you know the left side of the equation is never negative. -7x is only negative when x > 0, so put any x not greater than 0 into the equation. Mark down the points and then connect them

Hint: It's a sideways parabola facing the left, that is relatively wide.
