Question 347649: This is one problem that I need to get all of them right in order to get credit for any of them. I will also show what I got for some of the answers. I am just confused how to get the x-intercept.
The equation
9 x + 5 y + 2 =0
has the x-intercept_____ and the y-intercept_-2/5_ .
It defines a straight line of slope__-9/5__.
The line defined by the equation
6.5 x + 2.3 y + 7.1 =0
has the x-intercept_____ and the y-intercept__-7.1/2.3__ .
Its slope is__-6.5/2.3__.
The line defined by the equation
-4.2 x + 7.4 y - 3.6 =0
has the x-intercept_____ and the y-intercept__3.6/7.4__ .
Its slope is__4.2/7.4___.
I assume that the answers I got are right but I really can't figure out how to get the x-intercept. Even when I graph the line it still doesn't add up and is wrong. Please help me!

Question 347658:

I just do not understand this. I could really use help in even just comprehending what it is asking.
(1 pt) Suppose you are given a function y=f(x), and you consider shifting and reflecting the graph of f. Indicate whether the following statements are true (T) of false (F).
____The graph of g(x) = f(x) + 1 is obtained by shifting the graph of f up one unit.
____The graph of g(x) = f(x) - 1 is obtained by shifting the graph of f down one unit.
____The graph of g(x) = f(x - 1) is obtained by shifting the graph of f right one unit.
____The graph of g(x) = f(x + 1) is obtained by shifting the graph of f left one unit.
____The graph of g(x) = f(-x) is obtained by reflecting the graph of f in the y axis.
____The graph of g(x) = -f(x) is obtained by reflecting the graph of f in the x axis.
Note: In order to get credit for this problem all answers must be correct.
