You will sink the enemy ships in the coordinate plane by using the slope of the line.
After completing this tutorial, you will be able to complete the following:
This Activity Object provides practice calculating the slope of a line found on a coordinate plane.
In order to find the slope of a line, it is helpful to first find the vertical change in y (sometimes called the "rise") and the horizontal change in x (sometimes called the "run").
Note: This line has a positive slope - it slants upward from left to right.
Locate two points on a given line: (0, 1) and (3, 4).
Find the vertical and horizontal change:
The following key vocabulary terms will be used throughout this Activity Object:
· coordinate plane - a plane formed by the intersection of a horizontal number line (the x-axis) and a vertical number line (the y-axis) at their zero points (the origin)
· line - a straight path that is endless in both directions
· slope - the measure of steepness of a line
A slope can be:
o positive - slanting upward, from left to right
o negative - slanting downward, from left to right
o zero - if the line is a horizontal line
o undefined - if the line is vertical, it has no slope
