1.  The linear equation:
y = m x + b
m = 3
- 2 = 3 · 1 + b
- 2 = 3 + b
b = - 5
Answer: A ) y = 3 x - 5
2.  We will solve the system of equations:
12 = - 4 m + b  /  · ( - 1 )
23 =  7 m  +  b
----------------------
- 12 = 4 m - b
+
 23 =  7 m + b
--------------------
11 = 11 m,         m = 1,     b = 16
Answer:  A ) y = x + 16

5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?
Luda [366]
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.
