This week, we explored equations and patterns of lines on a graph.

Hint: parallel lines = same (m1 = m2)

perpendicular lines = reciprocals of eachother (m1 x m2 = -1)*

-The 2 equations we can use to find lines given a few clues are:

y = mx + b  OR

m = y-y / x-x

Example:

:

With linear equations, if we can figure out the slope and have enough hints, we can find an equation for each line.
