### Transcript

• 1. Algebra I CCP Quarter 3 Benchmark Review – Packet #1Find the equation of each line in slope-intercept form (y = mx + b).1. 2.3. 4.5. ` 6.
• 2. Graph the equations of the lines below in the form given. 21. y=  x 2. y = -x – 2 33. 4x – 3y = 12 4. x=4
• 3. 15. y= (x – 2) 6. y – 2 = -(x + 4) 4Find the x and y intercepts of the following linear equations and then graph.1. 6x – 12y = -36
• 4. Find the x and y intercepts of the following linear equations and then graph.2. x + 2y = 53. 0.8x + 0.3y = 2.4
• 5. Find the equation of a line given the slope and a point. Put in both point-slope and slope-intercept forms.1. m=3 (1, 4)2. m = 2 (2, −3)3. m = −1 (−4, 2)
• 6. Find the equation of a line given 2 points. Put in slope-intercept, point-slopeand Standard forms.1. (1, −5) (4, 7)2. (−3, 4) (0, 7)3. (5, −2) (−1, 0)
• 7. Rewrite the equation in slope-intercept form (y = mx + b). Solve for y.1. 4x – y + 3 = 0 2. 2x + 4y = -123. 2x – 4y = 20 4. 4x – 8y = -16Rewrite each of the following linear equations in Standard Form. 31. y= x–1 2. y = -x – 7 4 13. y – 5 = -2(x + 3) 4. y+2= (x + 5) 2
• 8. Parallel and Perpendicular Lines1. Find the equation of the line perpendicular to 4y - 2x = 6 and passes through the point (3, 1).2. Find the equation of the line parallel to 2y + 3x = 5 and passes through the point (−2, 5).3. Write the equation of the line that is perpendicular to the given line and passes through the given point. Then find the parallel line going through the point too.
• 9. Solve each of the following linear systems by graphing.1. 2x + y = 4 x+y=22. x − 2y = 2 2x + 5y = −5
• 10. Solve each of the following linear systems using the substitution method.1. 2x + 4y = 8 5x + y = -72. x + 2y = 3 2x + 4y = 6 13. y=- x-1 3 4x - 3y = 18
