Okay, here we have this:
Considering the provided graph, we are going to calculate the equation of the line, so we obtain the following:
We first calculate the slope using the following two points through which the line passes (-3, -2), (3, -4). So, we have:}
m=(y2-y1)/(x2-x1)
m=(-4-(-2))/(3-(-3))
m=(-2)/6
m=-1/3
Now, let's find the y-intercept using the slope and the point (-3, -2):
y=mx+b
-2=(-1/3)(-3)+b
-2=1+b
b=-2-1
b=-3
Finally we obtain that the equation of the line is:
y=mx+b
y=-1/3x-3
