Point-slope+equations

Review: slope: slope = rise/run slope-intercept equation: y=mx+b, m = slope, b = y-intercept equations of horizontal and vertical lines

y = m(x-a) + b

Using positive, negative and integer slopes, positive, negative and zero co-ordinates.
 * Level I: graphing given point and slope**

positive, negative and zero x- and y- co-ordinates
 * Level II: Identifying point and slope from equation:**

Using positive, negative and zero values for co-ordinates.
 * Level III: Writing the equation given point and slope**

Find the slope Substitute slope and one of the points
 * Level IV: Writing the equation given two points**

Multiply by the denominator Expand Simplify Move X to the left-hand side Make sure X-term is positive
 * Level V: Converting point-slope to scalar form/Verify that any point used will produce same equation**
