Answer:
y = -1/2x - 7/2
Explanation:
It is a little hard to read the graph, but I think that points (-5,-1) and (-3,-2) are on the line.
The slope is the change in y over the change in x.
-2 - -1/-3 - -5
-2+1/-3+ 5
-1/2 This is the slope.
I am going to use the point (-3,-2) to solve for the y -intercept.
slope = -1/2
y = -2
x = -3
y= mx + b
-2 = 1/2(-3) + b
-2 = 3/2 + b subtract 3/2 to both sides
-2 - 3/2 = b
-4/2 - 3/2 = b
-7/2 = b
y=mx +b
y = -1/2x - 7/2
