Answer:
In a coordinate axis, the horizontal line is called the x-axis, and the vertical line is called the y-axis.
1) Then if you have a point (x, y), to graph this you go at the horizontal axis to find the value x,
2) Starting from the point you already found, now you need to move y units in the vertical axis.
Now we want to graph the point (0, 3.5).
First we need to locate the value 0 in the horizontal axis, this is the point where both axes intersect.
Now we move 3.5 units, because the number is positive, we move 3.5 units upwards.
The graph of the point is shown below.
The Empire is attacking a Rebel base that is stocked with X-wings and
Y-wings. The Rebels need to build a fleet consisting of
ships (with at least 1 X-wing), to be led by 1 pilot in an X-wing.
There are ways of picking the leader, and
ways of building the rest of the fleet, so there's a total of
ways of building such a fleet.
In the other direction, suppose we build a fleet comprising of X-wings and
Y-wings. We have
ways of picking X-wings and
ways of picking Y-wings. Also from the
X-wings we pick 1 to be the leader, which we can do in
ways. So there are
ways of building such a fleet. But since
, we have
ways of building the fleet with these specifications. Sum over all possible values of ,
