the Y intercept of f(x) = -2/9x + 1/3 is 1/3
(third option !!)
K is opposite to 47 so k is also 47. I is opposite to 39 so I is also 39. You add all of those together making it 172. You then subtract it from 360.
So 47+47+39+39=172
360-172=188
188 is both j and opposite j so divide 188 by 2 and you get 94.
J=94

the equation of line is given by;
y-y1=m(x-x1)
Answer:
86
Step-by-step explanation:
Firstly,
Average = Sum/Number of Numbers
Since 7 grades' average is 77, so we can say:
77 = Sum/7
Hence, Sum = 77 * 7 = 539
Now,
81 - 18 = 63 [63 marks were recorded incorrectly. actual sum would be 63 more]
So,
Actual Sum should be 539 + 63 = 602
Actual Average = 602 / 7 = 86
Hence, actual report card average would be 86
