Answer:
a) the slope is 2/-1 or just -2
b) the slope is 1/1 or just 1
Step-by-step explanation:
You can find slope (rise/run) by picking a point on the graph. For example on question a I chose the point (-2, 1) i then counted how far my run was, which is 2, and my rise (or how far down it went) was -1. Therefore my slope was 2/-1 or just -2.
Differentiating w.r.t y,
We get,
<span>2 x (d x/d y) + y (d x/d y) + x + 2 y = 0 </span>
<span>Put
d x/d y = 0 </span>
The equation becomes:
<span>x=2 y </span>
<span>substituting into main equation
We, get
3 y^2 =9 </span>
y= √3
x = <span>± 2√3</span>

Answer:
With the narrower angle (15), they add cross supports. The wider angle (30) is given with no supports. Making a stable swing set is no joke.
