Graphing Linear Equations
Write the equation in slope-intercept form y
mx b, where m is the slope and b is the
y-intercept.

is in slope- intercept
form, y mx b where m
and b -3
m slope
rise 3 and run 2
5
Graphing Linear Equations
Since the y-intercept is 3, on the y-axis put a
point at 3
6
Graphing Linear Equations
The rise is 3 so count up 3 units.
The run is 2 so count 2 units to the right.
7
Graphing Linear Equations
Place a point here.
Count up 3 more units and to the right 2 units.
8
Graphing Linear Equations
Draw a line through these 3 points.

A2.2 continue to review the concept
of a line, write equations of lines
given various information, and graph
linear equations. Graphing
calculators will be used as a teaching
aid.
