ex. x=5

horizontal lines

ex. y=-3

scatter plot

a graph of non-linear data points

best fit line

the line that most clearly approximates the data in a scatter plot

slope intercept form

m= slope

Point slope form

y-y1 = m(x-x1), where m is the slope and (x1,y1) is the point the line is passing through.

standard form
