Step 1: Count your slope
(Clearly Identify 2 points on
the graph.
Then, starting at the point
furthest to the left,
count how many units you
must rise and run to reach
the 2nd point)
Step 2: Clearly Identify
the y-int
Step 3: Substitute slope for
the m & the y-int for b in the
equation y = mx + b
Ex2) Write the equation of the
line graphed below:
m = ____ b = _____
