Add 8 on both sides in order to isolate n:
-3 + 8 < n - 8 + 8
5 < n
Answer:
sin = opp/hyp
height = opp side
hyp = length of string
sin65 = height / 500
multiply both sides by 500
500 * sin 65 = height
use calculator
453.153893518324982 = height
~ 453 feet
The gradient of y axis is zero. Since the line is parallel to y axis, its gradient is also zero. This
y=mx+c
Where m is the gradient;
y=(0)x+c
y=c
Replacing for y and x;
0=0(-4)+c
c=0

The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -3), we can say (x1, y1) = (-1, -3)
So ,
Since the second point is (-4, -8), we can also say (x2, y2) = (-4, -8)
So ,
Put this all together to get: , , , and </span>
