-­‐1 2 4 5 8 -­‐2 4 8 10 16 Remember, y goes first (on top)! This is opposite of graphing ordered pairs, where you go x first (x, y). Slope-Intercept Form
y = Mx + B
Equation of a Line!
** Check your slope! ** Positive Slope Negative Slope Rate of Change Ex: Find the slope of the line
that passes through the points
(2, -3) (5, -6)
Ex: Find the slope:
y = -2x + 5
y = ¼x + 3
y=x
