Math Homework Help!
Posted:

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 yintercept and things like that. Please help!
1. Which equation has the same yintercept as y=4x3? A.y3=x B.y=8x+3 C.3y=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 yintercept as y=3x2? F.y2=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 slopeintercept 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!
