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)

For which values of A, B, and C
will Ax + By = C be a vertical line
through the point (9, 3)?
The equation for a vertical line through (9,3) is x = 9.
Thus,
A=1, b=0 and c=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 the system of equations using substitution:
4x + 3y = -8
y = 8x – 12
Plug in 8x - 12 for y
4x + 3(8x - 12) = -8
4x + 24x - 36 = -8
28x = 28
x = 1 (then plug in to find y)
x = 1 and y = -4
