Question 110795: Hi, I have a problem from my College Algebra homework that I need help with. Logically I think I managed to get the answer to Bob's salary for 2008, being $56K, but I am having a problem with the rest. Thank you for your help.
The following graph shows Bob’s salary from the year 2002 to the year 2005. He was hired in the year 2002; therefore t = 0 represents the year 2002.
The left of the graph is: 40000 - 50000 in 2000 increments. The bottom is 0 - 4 in 1 increment. The line is:0=4100; 1=43,5000; 2=46000; 3=48500.
a) List the coordinates of any two points on the graph in (x, y) form.
(___, ___),(___, ___)
b) Find the slope of this line:

Question 110843: I did this equation but I do not think it is right. Can you check it and if it is wrong can you show me what I did wrong.
4(x - 1) + 2 = 3x + 8 - 2x
this is what I did.
4x - 4 + 2 = 3x + 8 - 2x
-4 + 2= -2 and 3x - 2x + 1x
4x-2 = 1x + 8
subtract 1x from both sides and I got 3x
and add 2 to both sides and I got 10
3x = 10
x= 10/3 = 3 1/3
i do nnot know if this is right?
