Answer:
y=-11.88x-39.93
Step-by-step explanation:
Plot the data

on the coordinate plane using graphing calculator. Then use linear approximation y=ax+b and determine that a=-11.88, b=-39.93.
The line that best fits these data is

Answer:
Well yes because you do get an answer out that (a=4)
Step-by-step explanation:
Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
Answer:

Step-by-step explanation:
*it's kind of hard to read the number in parenthesis though but i think it's 5
both angles have to add up to 180º because they are co-exterior angles on parallel lines.
