Answer:

12/5

Step-by-step explanation:

To find the slope of the line, we'll need to use the below formula;


m=(y_2-y_1)/(x_2-x_1)

where x1 = -1, y1 = -4, x2 = 9, y2 = 20, so let's go ahead and substitute these values into our formula and solve for m;


m=(20-(-4))/(9-(-1))=(20+4)/(9+1)=(24)/(10)=(12)/(5)
