Answer:
23.3
Step-by-step explanation:
with the equation of the slope for two points given, m=Y2-Y1/ X2-X1, you can obtain the slope , x1= 3, y1 = -1 , x2= -1, y2= 2
m = 2-(-1)/ -1-3 ⇒ m= 3/-4, m = -3/4, therefore the slope is - 3/4
1/2 because you can simplify 4/8 and do 4 divided by 4 and 8 divided by 4 which is 1/2
