Semester One Exam Flashcards
l a x + b l = c (Remember, always isolate absolute value on the left first.)
ax + b = c or ax + b = -c (Remember, always isolate absolute value on the left first.)
l ax + b l < c (Remember, always isolate absolute value on the left first.)
-c < ax + b < c (Remember, always isolate absolute value on the left first.)
l ax + b l > c (Remember, always isolate absolute value on the left first.)
ax + b > c or ax + b < -c (Remember, always isolate absolute value on the left first.)

When finding the equation of a line, first find m and b, second write slope - int. form, and third change to standard form (Ax + By = C) A > 0; A, B, and C are integers.
