On which axis does the point 0 12 lie a positive x

This preview shows page 10 - 13 out of 13 pages.

On which axis does the point (0, - 12) lie? A. positive x-axis B. negative x-axis C. negative y-axis D. positive y-axis
Part 21 of 25 - 4.0/ 4.0 Points Question 21 of 25 4.0/ 4.0 Points Complete the three ordered pairs (3, ), (8, ), (0, ) so that they are solutions to the equation: x + y = 8
Feedback: Correct! You replace the x in the equation with the first coordinate of each of the ordered pair to solve for each corresponding y. E. (3, 3), (8, 8), (0, 0) Part 22 of 25 - 4.0/ 4.0 Points Question 22 of 25 4.0/ 4.0 Points Two lines have the same slope and different y-intercepts, how many points do they have in common?
Part 23 of 25 - 4.0/ 4.0 Points Question 23 of 25 4.0/ 4.0 Points Calculate the slope of the line between the points (0, 0) and (4, 4/9)
C. Slope is 9 D. Slope is 1/9 Part 24 of 25 - 2.0/ 4.0 Points Question 24 of 25 2.0/ 4.0 Points Find the slope and the y-intercept. Be sure to write the y-intercept as an ordered pair - in parentheses and with commas between the coordinates. y = 7x Slope is 7 and y-intercept is 0 . (0,0) Feedback: Once the equation is written in slope-intercept form, the coefficient of x is the slope and the constant is the y-coordinate of the y-intercept. Always be sure to show the y-intercept as an ordered pair in parentheses and with a comma between the coordinates!
Part 25 of 25 - 4.0/ 4.0 Points Question 25 of 25 4.0/ 4.0 Points Solve for y: 21x + 7y = 28
E. y = 3x + 25
