What is the slope of the line shown in the graph? a coordinate plane is shown with points graphed at negative 2 comma 2 and 0 comma 1. the points are joined by a line.

-1/2

Step-by-step explanation:

You mention a graph, but have not shared that graph.  However, your presentation of two points on this line is sufficient for the calculation of the slope of the line joining the two points.

The points are (-2, 2) and (0, 1).

As we move from (-2, 2) to (0, 1), x increases by 2 and y decreases by 1.

Hence, the slope of this line is m = rise / run = -1/2.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
