n__Slope-intercept formula__ for a straight line is

n

n *Y = mX + b *

n

n __Y and X__ = variables (scores) on the *Y *and *X* axes

n __m__* *= slope of
the line (a constant)

n __b__ = intercept (intersection) of line with Y axis

n __Positive__ Ð highest point on line is Right of lowest point

n __Negative__ Ð highest point on line is Left of lowest point

n __Equal__ Ð horizontal lines

n __Large__ (+ or -) Ð vertical lines
