What is an equation in point-slope
form of the line that passes
through (−1, −4) and (2, 5)?
FYI- this type of problem on the Final is way easier because of multiple choice!
y + 4 = 3(x + 1)
or
y - 5 = 3(x - 2)

Solve
5x + 2 − 2(x − 1) = 3x + 4
5x + 2 - 2x + 2 = 3x + 4
3x + 4 = 3x + 4
4 = 4

3=abs(6-x)
6 - x = 3 6 - x = -3
-x = -3 or -x = -9
x = 3 or x = 9

Solve using elimination
10x – 8y = 4
–10x + 6y = –18
When you add the 2 equations you get:
-2y = -14
y = 7
Then plug in y = 7
10x - 56 = 4
10x = 60
x = 6

Solve
x^2-2x-15=0
Factor: (x + 3)(x - 5) = 0
x + 3 = 0 or x - 5 = 0
x = -3 or x = 5

Solve by factoring (or quadratic formula)
7x^2+16x=-4
First, add 4 on both sides to get a zero.
Then, either AC method or guess & check to factor.
AC= 28 (so factors of 28 that add to 16: 14&2)
7x^2+14x+2x+4
Then group and factor the GCF
7x(x+2)+2(x+2)
Then factor out the (x+2)
(x+2)(7x+2)=0
Thus, x = -2 or -2/7

What are the coordinates of the vertex of (Hint: use -b/2a)
y=x^2+2x+8
-b/(2a)
is used to find the x value of the vertex
x=-2/(2*1)=-1
Then, plug x=-1 into the function to find the corresponding y.
f(-1)=(-1)^2+2(-1)+8
1 - 2 + 8 = 7
Thus (-1 , 7)
