1 BELL RINGER

2 POINT SLOPE - FORMULA y – y 1 = m(x – x 1 ) What does each variable represent? How can this formula be used?

3 POINT SLOPE - REVIEW y – y 1 = m(x – x 1 ) Write the equation of a line with a slope of -2 and goes through the point (2, 4). m = -2 (2, 4) y – y 1 = m(x – x 1 ) x 1 y 1 y – 4 = -2(x – 2) y – 4 = -2x + 4 + 4 + 4 y = -2x + 8

4 Carnegie Textbook PG. 230 #9 Write the equation of a line that passes through the given point and has the given slope. Then write the equation in slope-intercept form. Show all your work. POINT SLOPE - REVIEW

5 Carnegie Textbook PG. 232 #4 Find an equation of the line in slope-intercept form that passes through each given set of points. Show all your work. POINT SLOPE - REVIEW

6 Carnegie Textbook PG. 232 WRITING EQUATIONS

7 POINT SLOPE - PRACTICE Carnegie Skills Practice WS #1 – 28 all Vocabulary Writing Equations w/ slope and y-intercept Writing Equations w/ point-slope Writing Equations given two points Writing Equations from Graphs
