1) find an equation of the line point slope form that passes through (4,3) and is parallel to the line 3x-y=7
2) what is the equation in standard form of the line through (4,1) an (-2,3)?
3) find the equation of the line with x-intercept 5 and y-intercept 8
it would be great if someone could help me with these! :)

Question 181771: can you please help me do these problems?
solve by graphing method.
1)y - x = 4
y = 3x + 2
2)x + y = 1
5x + y =-7
3)4x + 2y =6
x - y =3
solve by the substitue method
4)
a=3b
a-5b=16
5)
8c-d=-3
4c+5d=15
6)
9p=2q-6
3p-q=12

Question 182030This question is from textbook College Algebra The Graphing Approach
: This is a two part question:
The function f(x) is graphed points are (3,-1), (1,0), (0,3), (-2,4)
Graph y=-f(x-2)
I'm not sure but I have the new points as (-3,-1), (0,1), (0,3) (2,4)
Could you check this for me
The funtion f(x) is graphed points are (3,-1), (1,0), (0,3), (-2,4)
Graph y=f(2x)
I have a TI-84 Plus - I'm not sure how to use it very well and my instructor doesn't give much in the way of using it. So I'm kind of lost.
Thanks for your help

Question 184941: I have to graph 3x + 2 = 5x - y. I can do some, like I already did y = 3x - 5 but I don't understand how to one like this. This is more difficult and am not sure about doing both sides????? I am in an online college so this is not from our text book. I guess because the answers are in the back!!!

Question 188892: if i give you two points on a graph say (5,20) and (8,29) where do i go if i do
20-29=-9
--------
5-8=-3 then i do
-9 / -3 getting 3 ok then i make a table knowing that the slope is 3? but then 0 or y intercept is 5 right but then they want me to solve algebra method where do i go next from there? do i make a graph or a rule first? because the rule would be y=5x-3 right?
