Answer:

Pretty sure it is A. y = -2x - 1

Step-by-step explanation:

y = mx + b

m is slope

b is y - intercept

y-intercept = point where line intercepts the y - axis. in this graph, it intercepts at (0, -1)

by counting the squares, you see this line has a rate of change of up two left one which is 2/-1 or -2. that is the slope

your photo is super blurry so it's hard to tell, but i'm 99% sure i am correct.

The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.

We need to find the slope-intercept equation of the line.

Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.

The coordinates of the line (-1, 1) and (1, -3).

The slope of the equation is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Now, m=-3-1/1+1=-2

Substitute m=-2, x=-1 and y=1 in y=mx+b.

That is, 1=-2(-1)+b⇒b=-1

So, y=-2x-1

The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.
