Part 1 of 25 - Default: 4.0/ 4.0 Points Question 1 of 25 4.0/ 4.0 Points Choose the slope and y-intercept of the equation: y = 7x + 4 A. The slope is 7 and the y-intercept is (4, 0) B. The slope is 4 and the y-intercept is (7, 0) C. None of these. D. The slope is 4 and the y-intercept is (0, 7) E. The slope is 7 and the y-intercept is (0, 4) Feedback: Right. You have used the slope-intercept equation of a line (y = mx + b) correctly.
Part 2 of 25 - Default: 4.0/ 4.0 Points
Question 2 of 25 4.0/ 4.0 Points Where does the point (0, - 3) lie?
Part 3 of 25 - Default: 4.0/ 4.0 Points Question 3 of 25 4.0/ 4.0 Points Choose the location of the point (1, - 16)
A. Quadrant I B. Quadrant II C. Quadrant III D. Quadrant IV Feedback: In Quadrant IV, the first coordinate is positive and the second coordinate is negative. E. Negative y-axis F. Positive y-axis G. Negative x-axis
H. Positive x-axis Part 4 of 25 - 4.0/ 4.0 Points Question 4 of 25 4.0/ 4.0 Points The equation of a line is x - y = 5. The intercepts should be written as ordered pairs - in parentheses and with a comma between the coordinates. It's x-intercept is: (5,0) It's y-intercept is (0,-5) Part 5 of 25 - 4.0/ 4.0 Points Question 5 of 25 4.0/ 4.0 Points The equation of a line is x = - 16. Its intercepts are:
C. x-intercept: (- 16, 0) y-intercept: (0, - 16) D. x-intercept: (- 16, 0) y-intercept: (0, 0) Part 6 of 25 - 4.0/ 4.0 Points Question 6 of 25 4.0/ 4.0 Points The point A is located on the x-axis, 6 units to the left of the y-axis. What are the coordinates of point A?
