Algebra Period 3 ( Review)

1) We know how to GRAPH a line by 3 points where we decide what to plug in and chug
Usually, we just try 0, 1, 2 first

2) We know how to GRAPH a line by intercepts...we plug in zero for y and x and chug
This works really well when the line is in STANDARD form and the coefficients are factors
of the constant on the other side of the equation.

3) We know how to GRAPH a line by using slope-intercept form... y = mx + b
We isolate y on one side
We read the y intercept (the b -> the constant on the other side)
We graph that value on the y axis
We COUNT to the next point by reading the slope, the coefficient of the x
The slope should be read what happens to the y value (+up or -down) and then what
happens to the x value (+ right or - left)
If the slope is not a fraction, make it a fraction by putting the integer over 1
