A should be the correct answer
Answer:

Step-by-step explanation:
To write the equation of a line use the point slope formula
. Find m by using the slope formula with the points.

Since the line is parallel, it will have the same slope.
Substitute m = -1/3 and (-3,-4).

Answer:
Step-by-step explanation:
3/4 x 9/4 = 1.6875 or 27/16
The mean is the average.
To solve for the average we add all the numbers up and divide by how many numbers there are.
21, 23, 25, 25, 26, 28, 28, 28, 31, 33.
268 total, now divide by how many numbers there are.
268/10
Your mean is 26.8
Y= 70° because the values in a triangle must equal 180 so,
60+50= 110
180-110= 70
and since x in this equation is the same as y, by default,
x= 70°
