Answer: Marianne would have to get a 79 on her final test.


Step-by-step explanation: In order to get the average, you have to add all of your numbers up and multiply by how many numbers you have (in your case, 3) and you will find your answer.

79+81+77=237  237 divided by 3 is 79. (  Sorry I used a calculator :(   )

Find the slope and y-intercept and tell me if its proportional or non-proportional.​
weqwewe [10]

Answer:

Slope: 6

Y-intercept: 0

Proportional

Step-by-step explanation:

The equation for this table is y = 6x + 0 or just y = 6x.

y         =            6x           +                0

y-value          slope (x-value)           y-intercept

Proportional because it crosses (0,0) on the graph.
