WHOEVER ANSWERS FIRST WILL MARK BRAINLEST Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation:
a) y = 3.5x + 4; A(...; 5), B(10; ...)

b)7x − 5y = 12; A(...; 9), B(4; ...)

c)y = − 37 x +3; A(...; 6), B(9; ...)

d)y = 0.3x + 1; A(...; 9), B(5; ...)

please answer asap

Anormally distributed data set has a mean of 176.3 and a standard deviation of 4.2. what is the approximate z-score for the data value of 167.9? 2.00 −2.00 8.4 −8.4

Ineed to know the answer to this algebra question.

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
