I am in an elementary calculus class and I am struggling with my first assignment 1) because my new teacher is tough to understand. and 2) because my course load has increased significantly, so I have realized I need more time dedicated to my math.... anyways any help IS appreciated.

1) So I'm Sitting here looking at a function and I am getting ready to throw the book out the window. so the questions is what do all family members of f(x)= 1 + m(x + 3) have in common. so i have placed different values in the x, and then all i get is 1 + (insert growing # here)m like i know that i have my formulas y=mx+b, or y-y1=m(x-x1) but I just can't seem to find what they have in common.

2) This is my second question. I know it is a lot for a first post however i will try and provide as much as help when I'm smarter . anyways the question is... Show the area of a triangle with sides of lengths a and b and with including angle(theta) is

A=1/2absin(theta)

all i have is a right triangle in quadrant 2(thats sin right??) with a on my x axis, b on my y axis, (theta in the 45 degree angle) and I am lost.
