Answer:
C
Step-by-step explanation:
So, we want to find the equation of the line graphed.
To do so, let's first find the slope. Let's pick two points from the graph. I'm going to use (-2,2) and (0,-1).
The formula for slope is:
Let's let (-2, 2) be (x₁, y₁) and let's let (0,-1) be (x₂, y₂). So, substitute:
Subtract:
So, our slope is -3/2.
Now, we can use the point-slope form, which is:
Where m is the slope and (x₁, y₁) is any point on the graph.
Since our answer choices are using the values 2 and 4, this means we can use the point (2,-4).
So, (2,-4) is our (x₁, y₁).
Also, our m is -3/2. So, substitute these into the point-slope form:
Simplify:
Therefore, our answer is C.
And we're done!
