Step-by-step explanation:
Simplify
For the mean you add them all up and divide by the ammount of numbers you added. So it would be 118
Answer:

Step-by-step explanation:
Subtract 7 From both sides

7-7 = 0, 16 - 7=9
That leaves

Answer:
A) y = -1/2x + 1/2
Step-by-step explanation:
Find the y-intercept(when x = 0), which is 1/2.
Find the slope: m = y2-y1 / x2-x1
I used points: (3, -1), (-3,2)
m = 2 - (-1) / -3 - 3
m = 3 / - 6
m = -1/2
plug this into the slope intercept form equation: y = mx + b
y = -1/2x + 1/2
Answer:
y=6x-8 is the answer
Step-by-step explanation:
the formula is y=mx+b. m is the slope and b is the y intercept.
