Graphing Standard Form of a Line (ax + by = c)

1. To find the y-intercept, plug 0 in for y and solve for x.  Plot (0, y).

2. To find the x-intercept, plug 0 in for y and solve for y.  Plot (x, 0). 

3. Draw the line that passes through both of these points.  Be sure to extend it and draw your arrows.

Graphing Slope-Intercept Form of a Line (y = mx + b)

m = Slope

b = y-intercept (beginning pt)

1. Plot the y-intercept.

2. Plot your slope repeatedly (rise over run). 

3. Draw the line that passes through both of these points.  Be sure to extend it and draw your arrows.

Arithmetic Sequence Notes

An arithmetic sequence is a sequence where the same number is being added repeatedly.

Geometric Sequence Notes

A geometric sequence is a sequence where the same number is being multiplied repeatedly.
