Can someone give me the answer and explain how please?

Answer:
The answer to your question is m = -1/3
Step-by-step explanation:
Process
1.- Get two points from the graph
A = (2, 0)
B = (-4, 2)
2.- Find the slope of the line
slope = m = (y2 - y1) / (x2 - x1)
x1 = 2 y1 = 0 x2 = -4 y2 = 2
-Substitution
m = (2 - 0) / (-4 - 2)
-Simplification
m = 2 / -6
m = -1/3
Answer:
-1/3
Find two points where the line intersects with a grid line, like (2,0) and (-1,1) then plug in one y and subtract it by the other y, and do it in the same order for the x on the bottom. in this case iys 0-1/2+1 (because it's negative), which gives us -1/3
