A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = −10x + 3000.

Answer:
Step-by-step explanation:
To graph the equation of line, we need to find the intercepts:
1) To find x-intercept: put y = 0
0 = -10x + 3000
Solving for x:
10x = 3000
x = 3000/10 = 300
A( 300, 0)
2) To find y intercept: put x = 0
y = -10(0) + 3000
y = 3000
B(0,3000)
Now plotting line through these two points gives the graph.
3) To find the slope of the equation:
Using two point form:
m = -10

To do this, we must set up ratios:
Option One:
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
The third option costs $0.00565/gram.
Therefore, option three is the cheapest!
