Answer:
y = -2x+2
Writing the slope was the more difficult part. Writing the y-intercept was the easiest because I had to select to points on the line and solve to get the slope. The y-intercept was already explicitly shown on the line.
Step-by-step explanation:
y = mx+b
y = -2x + 2
Answer:
Subtract the sum of the from the two angles 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the Value of X.

Answer:
Median = 116.
First quartile = 102.
Step-by-step explanation:
There is a total of 280 scores so the median will be the 140th score.
The first box gives 26 , second 34 = 60
The 3rd box contains 100 giving a total of 160 so the median lies in this third box.
140 - 26 - 34 = 80..
That gives a value of 80 / 5 = 16.
The median is 100 + 16 = 116.
The lower quartile is the 70th score
26 + 34 + 10 = 70.
So it is 100 + 10/5 = 102.
Add 222 and 194 together; 416. Then subtract; 627 - 416 = 211. Add one because that means she got over 627. She needs to get a score of 212 to beat the record. I hope that helps!
