It is proportional because all the points if put in fraction form equals 1/5. For 1 plant, he has 5 roses, and for 2 plants, he has 10 roses. 2/10=1/5. 3/15=1/5. 4/20=1/5. They all have the proportions of 1 plant per every 5 roses

The mean weight of five complete computer stations is 167.2 pounds.
The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165 pounds, and 178.2 pounds.
We have to determine the weight of fifth computer station.
Let the weight of fifth computer station be 'x' pounds.
Mean is calculated by sum of all the observations divided by the total number of observations.
So, 



x= 171.6 pounds
The weight of fifth computer station is 171.6 pounds.
Answer:y=2x+7
Step-by-step explanation:
so for the new equation, we know the slope is going to be the same (because its parallel) so for starters we have y=2x+b so now in order to find b (the y-intercept) we have to plug the point into the equation. So it would look like -1=2(-4)+b and then you solve for b and get 7 for b. SO the final answer is y=2x+7.
