9x-5x=7-3
4x=4
x=1
You know they are parallel because the lines will never intersect or meet. (Two straight lines usually mean it is parallel)
Answer:
D
Step-by-step explanation:
The correlation coefficient r=-0.84 denotes that there is inverse relationship between x and y. It means that as the x values increase the y values decrease whereas as the x values decreases the y-values increases. Also, r=-0.84 denotes the strong relationship between x and y because it is close to 1. So, r=-0.84 denotes that there is strong linear relationship between x and y with smaller x values tending to be associated with larger y values.
The awnser is D but could also maybe be B
