1. 1. 1.solve for j 2. Find the GCF of 27, 54, 63 3j 4 12 6 3. Frank has purchased 50 candy bars to make cookies. If he uses 2/3 of a candy bar for each cookie, how many will he be able to make?4. Pablo has a board that is 4 ½ feet long,and he wants to cut it into three pieces allof the same length. Find the length ofeach of the three pieces.
2. 2. Study your vocabulary: relation, function, domain,range, etc. Write the formulas for this unit: Standard Form, Slope-Intercept Form, Point-Slope Form (coming soon) Know which form to use and how to write an equation and graph a line given: a. two points b. a point and the slope c. the interceptsBe able to: a.) describe the slope of a straight line b.)explain how a slope of 2 is different than a slope of½. c.) explain how a positive slope differs from anegative slope d.) explain the characteristics of ahorizontal and vertical line
3. 3. 1f 2 g 1
4. 4. y2 y1m x2 x1
5. 5. Find the slope of the line thatpasses through the given pointsand identify what type of slopeit is:1. (-1, 2) & (3, 4) 2. (1, 2) & (1, 3)3. (-1, -2) & (-4, 1)
6. 6. y = ½x - 1
7. 7. Write an equation given two points: (1,1) (5,1)Steps:1. Find the slope.2. Choose one of the points to use.3. Substitute the values of m, x, and y into the slope- intercept form and solve for b.4. Write the slope-intercept form using the values of m and b.
