Answer:
(a) 
(b) 
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis
Step-by-step explanation:
We have given points are 
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by 
So 
(b) Equation of line is given 
This line is parallel to x axis so slope will be zero
So equation of line will be 
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis
Answer:
After taking the first exam, 15 of the students dropped the class. The value 15 describes a characteristic of a population - first choice.
Answer:65
Step-by-step explanation:
I'm not sure what you mean by "expression form," but if its simpliest form, you would simply do 20+5*9, and 5*9 is 45. 45+20 is 65
The value of x is 18. They are parallel lines cut by a transversal, that means you have to set them both equal to each other in order to find x.
