# A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is #y=-10x+3000#, how do you graph and Interpret the x-intercept and the slope?

##### 1 Answer

See description

#### Explanation:

You have to try and understand what the numbers are doing and associate that with actual events.

It is stated that

The right hand side (RHS) has negative

The

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At the point where the graph crosses the x-axis it means that

Consequently the x-intercept is at the point of reaching the ground.

The slope is the rate of descent which is constant as time (x) increases.

Actually the rate of descent is a very rounded value. To 2 decimal places I think it is 9.81 metres per second per second in metric form.

In imperial form it is something like 32.2 feet per second per second.
