Study Guide for Quiz 2 for Graphing Chapter Writing equations: 1. Write an equation given the slope and the y-intercept. 2 m = 3 and y-intercept = (0, 5) 2. Write an equation of the following lines (A & B) and identify the slopes of each. A A. slope = ___________ equation = ___________ B. slope = ___________ equation = ___________ B 3. On the following graph, graph the two lines y = 1 and x = -1. 4. Write the equation of line A and B. Equations: A. ______________________ B. ______________________ A B 5. Write the equation for a line that contains a slope of 2 and a point (1, 3). 6. Write the equation for a line that contains a slope of -5 and a point (-6, 4). 7. Write the equation of a line that contains (1, 4) and (3, 8). 8. Write the equation of a line that contains (4, -1) and (-2, 8). 1 9. Graph the following two lines on the graph below: A. y + 3 = 2 (x – 4) B. y – 1 = – (x + 3) *Hint, find slope and a point (Remember, points come out with opposite signs.) 10. Are the following lines, parallel, perpendicular, or neither? A. x = 2 B. y = 7x y = –5 y – 28 = 7(x – 4) 11. Write an equation in slope-intercept form for the line that passes through (0, 6) and is parallel to y = 2x + 3. C. 2x – y = 1 x – 2y = –4 D. y = 6x – 2 x + 6y = –48 12. Write and equation in slope-intercept form for the line that passes through (5, 2) and is perpendicular to y = –4x – 3.
