A "?" is a graph in which two sets of data are plotted as ordered pairs in a coordinate plane. 11. If line K1 has a slope of 2/3 and K2 has a slope of 2/3, are the lines parallel? 12. A " ? " is described by an equation of the from y = kx 13. Find the slope of a line that passes through (1,3) and (-2, -6) 14. Lines where the product of the slope is -1 are _______. 17. Are the lines perpendicular? m1=1/4, m2=-4 19. As x decreases, y decreases this is called a ________ correlation. 22. As x increases, y increases this is called a ________ correlation. 24. True or False, the change in x is over the change in y. 25. Y= 4/5x + 10, What is the y-intercept?

Down 1. An equation generated using the coordinates of a known point and athe slpe of the line is " ? " 2. Lines that have the same slope are ________. 4. The calculator uses a statistical method to find the line that most closely approximates the data. The line is called the "_?_" 6. An equation of the form y=mx + b is in "?" form. 7. A line with a slope of 0 is a ________ line 8. A slope with 0 on the bottom i.e 5/0 is what? 9. b is representative of "what value" is our equations 15. If the data points do not all lie on a line, but are close to a line, you can draw a "_?_" 16. Slope is the ratio of the change in y (rise) to the change in x (?) 18. An undefined slope is represented by a ________ line. 20. Y = 1/2x - 21, What is the value of slope? 21. The "?" of a line is a number determined by any two points on the line. 23.
