You can also graph the functions to compare them. Go to your math tools and open the Graph tool to graph the two linear functions. To create a graph, select the linear relationship and then enter values for the variables. Paste a screenshot of the two functions in the space provided. How could you find which puppy had the greater initial weight from the graph? How could you find which puppy gained weight the slowest?

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1. perpendicular

2. parallel

3. perpendicular
