can someone answer and explain I don’t understand at all ILL MARK BRAINLIEST

Answer:
A (4-7)/(5-3)=-3/2=-1.5
B (7-4)/(3-5)=3/-2=-1.5
C (d-b)/(c-a)
D (b-d)/(a-c)
Step-by-step explanation:
Identifying (x₁,y₁) and (x₂,y₂). We will use the formula to calculate the slope of the line passing through the points
slope =(y₂-y₁)/(x₂-x₁)
