Answer: -2
Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is and slope can be found using the ratio rise over run between any two points that are on that line.
When finding the slope, first look at y-intercept.
We can see that a point crosses it at 2 units up.
From there, the tie it touches a point
would be to the right 1 on the x-axis.
So the slope is -2/1.
Since we go down 2 and to the right 1 or -2.
