The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130
In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110

Answer: y-6 = 0.5 (x-8)
Step-by-step explanation:
y − y1 = m(x − x1)
The equation is useful when we know:
one point on the line: (x1,y1)
and the slope of the line: m,
and want to find other points on the line.
Have a play with it first (move the point, try different slopes):
Look at it this way 1(700)*1(20). can u do it now?
