Answer:
The slopes of three sides of triangle are as follows: 
AB = -3
BC = 2/3
AC = -1/4
Step-by-step explanation:
The slope is denoted by m and is calculated using the formula

The given vertices are:
A(-2,4) B(-1,1) C(2,3)
The sides will be:
AB, BC, AC
Let m1 be the slope of AB
Let m2 be the slope of BC
Let m3 be the slope of AC
Now

Hence,
The slopes of three sides of triangle are as follows: 
AB = -3
BC = 2/3
AC = -1/4
 
        
             
        
        
        
Answer:
2
Step-by-step explanation:
We have two points so we can find the slope
m = ( y2-y1)/(x2-x1)
     = ( -11 - -1)/( 4 -9)
     = (-11+1)/( 4-9)
     -10/ -5
    = 2
