1. Slope
1.1. Rise over run
1.2. y2-y1 over x2-x1
1.3. change in y over change in x
2. Graphing Linear Equations
2.1. Graph y=m+b
2.1.1. graph the y intercept (b)
2.1.1.1. then do rise over run
2.2. Graph standard form
2.2.1. Ex- 4x+5y=20
2.2.1.1. plug in 0 for y to find out the x-intercept
2.2.1.1.1. then solve. x =5
2.2.2. plug in 0 for x to find out the y intercept
2.2.2.1. then solve. y=4
2.2.2.1.1. plot (0,4) on the graph
3. Vertical lines
3.1. have the same slope
3.2. points will have the same x value
3.3. equation of vertical line is x=b
3.4. go up and down
4. Slope intercept form
4.1. Y=mx+b
4.2. m=slope
4.2.1. b=y intercept
