Answer:the slope of this graph is
-(3)/(1)

Explanation:

You can find the slope by choosing any two ordered pairs in this case I choose (2,-4) and (-1,1). The you find the run and rise. Slope=
(rise)/(run), the run was 3 up and the run was 1. And it is negative because it is going down to the right.

You can find the slope either by just looking at the line or using the slope formula.

#1: The slope formula is:


m=(y_2-y_1)/(x_2-x_1) Find two points and plug it into the formula

I will use (0, 2) and (1, -1)

(0, 2) = (x₁, y₁)

(1, -1) = (x₂, y₂)


m = (y_2-y_1)/(x_2-x_1)


m = (2-(-1))/(0-1) [two negatives cancel each other out and become positive]


m=(2+1)/(-1) =(3)/(-1)

m = -3

#2: To find the slope without having to do the work, you use this:


m=(rise)/(run)

Rise is the number of units you go up(+) or down(-) from each point

Run is the number of units you go to the right from each point

If we start at a defined/obvious point, like (0, 2), find the next point and see how many units it goes up or down and to the right. The next point is (1, -1), so from each point, you go down 3 units and to the right 1 unit. So your slope is -3/1 or -3. You can make sure the slope is right by looking at another point.
