1. Graphing Functions x f(x) = 2x + 7 2 2(2) + 7 = 11 3 2(3) + 7 = 13 4
2(4) + 7 = 15 5
2(5) + 7 = 17

2. T - Tables The most basic method
Make a T-Table, using values of x of your choosing
(since you can choose, pick easy values to calculate)
Plot the points
Connect the dots x
f(x) = 2x + 7 2
2(2) + 7 = 11 3
2(3) + 7 = 13 4
2(4) + 7 = 15 5
2(5) + 7 = 17

3. Using Function Properties Often the fastest method
Slope Intercept Form: y = mx + b
Start at the y intercept, (0, b)
Remember slope is rise / run
Write the slope as a fraction
From the y – intercept count up the rise, then over the run
Given a slope and a point:
- Do the same as above, but start at the given point.
Graph y = 2x + 1
Start at (0,1)
Slope is 2/1
Count up 2 right 1

4. Using Function Properties Often the fastest method
Standard Form: Ax + By = C
Find, x-intercept and
y-intercept.
2. Plot those two points
3. Draw a line through them.
Graph 2x + 3y = 6
x-intercept: 2x = 6, x = 3, So, (3,0)
y-intercept: 3y = 6, y = 2, So, (0,2)
