slope = 2 & y-intercept = 3
y = 2x + 3
slope = -5 & y-intercept = 9
y = -5x + 9
slope = 1 & y-intercept = -4
y = x - 4
slope = -6 & y-intercept = -8
y = -6x - 8
parallel lines
Two lines in the same plane that never intersect.
linear regression
a method that graphing calculators use to find a precise line of fit that models a set of data.
causation
when a change in one variable causes a change in another variable.
y = 3x - 2
y = -2x + 3
