Question

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

y = x - 1
y = 2 x + 1
y = -4 x
y = x + 1

Answer 1

Y=-x-1

Step-by-step explanation:

(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!
