Answer:option 3 is the correct answer.
Step-by-step explanation:
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the graph given,
y2 = 3
y1 = 1
x2 = 0
x1 = - 1
Slope = (3 - 1)/(0 - - 1)
Slope = 2/1 = 2
