The gradient formula is (y2-y1)/(x2-x1) aka rise/run, where by (x1,y1) and (x2,y2) are two points on the line. 
In this case, the gradient
= -5-(-2))/(2-(-2))
= -3/4
        
             
        
        
        
Answer:
Step-by-step explanation:
First problem:
blank 2) on the left: PR = PQ + QR
blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore: 
2PQ = PR
2PQ = PQ + QR
blank 4) on the right: Subtract PQ from both sides, therefore
2PQ = PQ + QR
2PQ - PQ = PQ + QR - PQ
PQ = QR
 
        
             
        
        
        
Area of Rectangle = Width × Length
Area = 600 Sq ft
Width = 20
Length = L
20L = 600
L = 600/20 = 30
Floor is 30' long
