Since it's perpendicular to the line with the slope 5, you take the reciprocal of 5 which is 1/5 and change the sign: -1/5. So you have the equation: y=-(1/5)+b. To find b you substitute x and y for the coordinate (10,8).
y=(-1/5)x+b
8=(-1/5)10+b
8=(-10/5)+b
8=-2+b
+2 +2
10=b

So your new equation is: y=1x+10

Tyler wants to calculate his grade in his accounting class. His test grades are a 77%, 62% 85%, 80%. What is his average in the

swat32

Answer:

Step-by-step explanation:

Given Tyler test grades to be 77%, 62% 85% and 80%, to find its average in the class, we will find the mean of his grades.

Mean is the ratio of the sum of the grades to the total number of grades given.

$mean (\overline x) = \frac{\sum Xi}{N}$

Xi are the individual grades

N is the total number of grades = 4

$\overline x = \dfrac{77+62+85+80}{4} \\\overline x = \frac{304}{4}\\ \overline x = 76 % \\$

Hence his average in the class is 76%
