Cover up method is shown here
You could also choose to use the original equation and set one variable equal to zero
5
6
x- and y- intercepts found and then plotted on their respective axises
The intercepts were found by setting one variable equal to 0 but the cover up method is within there starting at the 3rd line

Fill in the Blanks
Type answer...
12
Use any two points to find the rise and run - you may need to simplify
Here the up 1 is +1 and right 3 is +3 so the rise over run is 1/3

14
(x1,y1) and (x2, y2) were labeled in the graph
You can use any two points that are on the line
Be careful with those negative signs!

y = mx + b
m is slope
b is the y-intercept

Positive rise is up and negative rise is down
positive run is right
negative run is left
It is easiest to always apply a negative sign to the rise so then you are always moving right for run

22
You begin on the y-axis at -4 since this is your b
slope tells you how to move to the next point (see picture)
