Ok, I'm usually good at math but I'm at a loss here. My teacher explained this but I don't get it! I remember mx+b but it's not helping. She assigned it to us for the weekend and most of the questions are similar but with different numbers, so I chose 5 out of 28. Can you guys help me solve them and explain and show the work for me? It'll help me understand so I can finish the rest of this, plus none of my friends are responding to me at the moment so you guys are the best thing I have. some of the questions are multiple choice too. They are about y-intercept and things like that. Please help!

1. Which equation has the same y-intercept as y=4x-3?
A.y-3=x
B.y=8x+3
C.3-y=4x
D.y=-3+8x

2.Which of the following is the equation of the line that has the same slope as y=-3/2x+2 and the same y-intercept as y=3x-2?
F.y-2=-3/2x
G.-3/2=y+2
H.y+2=-3/2
J.-3/2x=y+3

3.A software company started with 2 employees. in 6 months, the company had 7 employees. The number of employees increased at a steady rate. Which equation models the relationship between the number of employees n and the number of months m since the company started?
A.n=5/6m+2
B.m=2n+5/6
C.n=6/5m+2
D.m=5/6n+2

4. A line passes through the points (0,3) and (1,5). Graph this line and find an equation for the line in slope-intercept form. Show your work.

5.Find the slope of the line that passes through each pair of points. (-2,8),(5,-1)

Thanks in advance!
