What is equation of the blue line

-1

Step-by-step explanation:

To find the slope, you find the change in y over the change in x. In other words, you find the rise over the run.

If we just look at any square the line runs through, we see that the line goes down one, and goes right one. The "rise" is -1 (this is negative, because the line goes down towards the negative y direction), and the "run" is 1 (this is positive, since the line goes towards the positive x direction). This means that the slope is -1/1, or just -1

Slopes have equation y=mx+b. We found that the slope is -1, so we have y=-1x+b so plugging in any point, say (0,-1), we get -1=0+b, so b=-1. This gives the equation y=-1x+b, or just y=-x+b

Step 1) Pick two points on the line

Point 1: (0,-1)

Point 2: (-2,1)

Step 2) Use those points to find the slope

m = (1 - -1) / (-2 - 0)

m = (1 + 1) / -2)

m = 2 / -2

m = -1

Step 3) Plug in the slope and one point on the line into the slope-intercept form equation and solve for b, the y-intercept

y = -1x + b

-1 = -1(0) + b

b = -1

Step 4) Plug in the slope and the y-intercept into the slope-intercept form equation to get the final equation of the line

y = -1x - 1

Hope this helps! :)
