Equations of Lines

Let's graph a couple:

y = ( -3 / 5 )x + 4 ... start with the + 4

 

1 )The y-intercept is 4:

Graph of the point ( 0 , 4 )

2 )The slope is-3 / 5.  From the y-intercept...

 Graph of a line that goes through the points ( 0 , 4 ) and ( 5 , 1 ) ... go down 3 ... and over 5

 

TRY IT:

Graphy = 4x - 2
