Question

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

Answer 1

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:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{0-3000}{300-0}$

m = -10
