You can set a common label to connected resources and then delete by --selector

$ kubectl delete all --selector=<key>=<value> -n <namespace>
or 
$ kubectl delete all -l <key>=<value> -n <namespace>

In your file modify like following and apply above command

apiVersion: v1
kind: Service
metadata:
  name: echo1
  labels:
    app: echo1
spec:
  ports:
  - port: 80
    targetPort: 5678
  selector:
    app: echo1
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: echo1
  labels:
    app: echo1
spec:
  selector:
    matchLabels:
      app: echo1
  replicas: 1
  template:
    metadata:
      labels:
        app: echo1
    spec:
      containers:
      - name: echo1
        image: hashicorp/http-echo
        args:
        - "-text=echo1"
        ports:
        - containerPort: 5678
