Answer 1

##data is not given, using some dummy data
actual_price<-runif(15)
predicted_price<-actual_price+runif(15)
par(mfrow=c(1,2))
plot(predicted_price,actual_price,main="predicted price vs actual price",xlab="predicted",ylab="actual")
predicted_price=actual_price
plot(predicted_price,actual_price,type="l", lty=3,main="when predicted price = actual price",xlab="predicted",ylab="actual")
