## Review of Unit 7, Lesson 21. If a line is vertical (goes straight up and down), what kind of slope does it have?- 4, 4, - 3, 3, 2. Which of these points is on the line y = x %2b 3? TRUE, FALSE results history , , 3. y = 3x %2b 5, y= 5x %2b 3, y = -3x - 5, y = 3x - 5, 4. y equals -2.jpg, , , 5. x = 2, y = 2, x = -2, y = -2, 6. The graph of x = - 3 is a horizontal line (goes side to side). (2, 0), (0, 3), ( - 5, 7), (1, 6), 7. For the equation y = 2x %2b 1, what is the y-intercept? positive, negative, 0, undefined, 8. In y = mx %2b b, the %22m%22 is the slope. yes, no, Not enough information, 9. In the equation y = - 4x - 3, what is the slope? y = 2x %2b 4, y = 4x %2b 2 quiz , y = - 2x %2b 4 print quizzes , y = - 4x - 2, 10. If slope of a line is 3 and the y-intercept is -5, which of the following is the equation to this line? y equals 4x minus 2.JPG, , build your own quiz , 11. The graph of y = 4 is a horizontal line (goes side to side). positive, negative, 0 , undefined, 12.
