2. 6.0/7.0/8.0 Graphing Cheat Sheet
Slope y – intercept Form Vs. Standard Form
y = mx + b tells us nothing
m: slope to graph:
b: y – intercept find and plot intercepts
- convert to y = mx + b
Point - Slope Form:
y – y1 = m(x – x1)
(x1 , y1): point
m: slope

3. 6.0/7.0/8.0 Graphing Cheat Sheet
A point is a solution if it makes a true statement
Horizontal vs. Vertical
m = o m = undefined
Ex: y = Ex: x = 2
Parallel vs. Perpendicular
- Same slope, - opposite reciprocal slopes
different y –
intercept
