To find the slope of the line, choose any of the points in the table and set up this expression:
y2 - y1 / x2 - x1, where y2 is the y coordinate of the second point you chose, y1 is the y coordinate of the first point you chose, x2 is the x coordinate of the second point you chose, and x1 is the x coordinate of the first point you chose.
So,
3 - (-6) / 2 - 2 = 9 / 0 for the first two points. The slope of the line is undefined because it is a vertical line.
Distributive property means that you have to multiply everything directly outside the parent hes to everything inside the parentheses. For this problem multiply 7 to the 9x and to the -9 like so:
7(9x) + 7(-9)
63x + (-63)
63x - 63

Answer:
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
Step-by-step explanation:
Solution:
Suppose grade breakdown for certain college course is as follow:
Homework = 15%
Quizzes = 20%
Project = 10%
Test = 40%
Final exam= 15%
Let G represent the final grade
H represents homework average,
Q represents quizzes and P represent project, T represent test average and F represent final exam.
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
