Use the line tool to graph the equation on the coordinate plane y=-x

A screenshot of the graph is attached.

Explanation:

The y-intercept of a graph, where it crosses the y-axis, will be the point where x=0.  In this case, if x=0, y=0; this makes the origin (0, 0) the y-intercept.

The slope of this line is -1.  This means that for every increase of 1 in the x-axis, the y-coordinate will decrease by 1.  

This tells us that from (0, 0), the graph will go to (1, -1); then to (2, -2), (3, -3), etc.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
