What is the equation of the function that is graphed as line a ?

y = 2 x - 1
y = - x - 1
y = - x
y = 3 x

Y=-x-1

Step-by-step explanation:

Go to (0,-1) on the graph.

(Since that is the y intercept)

Now go down one and over one to the right. If the place you ended up was on the line, then that means that equation is your answer. Since y=-x-1 is the only equation where your finger ends up on a line, 5hat is the answer

Another way you can do this is by looking at where the line first meets the y-axsis which is at (0,-1)

Then take any two points on the line

(1,-2)

(2,-3)

And use the slope formula, y2-y1/x2-x1

Where y2=-3

Y1=-2

X1=1

X2=2

So

-3+2/2-1=-1

So the slope is -1 and y intercept is -1

Let’s plug those values in:

Y=-x-1

Hope this helps!
