Answer:

Slope = -3, Y-intercept = -2, y = -3x -2

Step-by-step explanation:

There are multiple points plotted on the graph, but right now, we only need to focus on two.

(-2, 4) (-1, 1)

Using the ordered pairs, do delta y/ delta x to get the slope

(1-4)/(-1-(-2)

(-3)/(-1+2)

(-3)/(1)

Slope = -3

y = -3x + b

As shown on the graph, the y-intercept is -2. It is when x = 0

So, for the equation, substitute the found values.

y = -3x -2
Y-intercept = -2

Slope = -3

Equation: y = -3x -2

EXPLANATION: y = mx + b

your b is -2 and your mx is -3
